Nissan Navara Diesel Injector Guide: D22, D40 & NP300

Nissan Navara diesel injectors vary significantly between the D22, D40 and NP300/D23 generations. Although these vehicles share the Navara name, they do not all use the same engines, fuel injection systems or replacement injectors.

The D22 and D40 ranges include 2.5-litre YD25 diesel engines with different Denso injector applications. The later NP300/D23 uses a 2.3-litre YS23 engine family with Continental/VDO common rail injection equipment in relevant Australian models.

Choosing the wrong injector can mean purchasing a component that does not match the engine's specifications or calibration requirements.

This guide explains the main Nissan Navara injector differences, how to identify the correct Denso or VDO reference, common failure symptoms, injector coding and the fitting components to consider before replacement.

DieselInjectors.com.au supplies genuine OEM diesel injectors across Australia, with parts identification assistance and professional workshop services available in Brisbane.

Nissan Navara D22 vs D40 vs NP300: Injector Comparison

The first step in finding the correct injector is identifying the vehicle generation and engine.

Nissan model	Engine	Injector manufacturer	Common injector reference
Navara D22	2.5L YD25 common rail, selected applications	Denso	095000-6240
Navara D40	2.5L YD25 common rail, selected applications	Denso	095000-6250
Pathfinder R51	2.5L YD25 common rail, selected applications	Denso	095000-6250
Navara NP300/D23	2.3L YS23, selected applications	Continental/VDO	A2C3335190080

These are common Australian catalogue references, not universal part numbers for every vehicle in each generation.

Some Navara models were offered with different engines, fuel injection equipment or market specifications.

Understanding the Nissan Navara Diesel Generations

The Navara name covers several different vehicle generations sold in Australia.

Knowing which one you have is essential when purchasing diesel fuel injection components.

Nissan Navara D22

The D22 was sold in Australia across a long production period with different engine options.

Later 2.5L YD25 common rail models are commonly associated with genuine Denso injector reference 095000-6240.

However, not every D22 uses this injector.

Earlier models and vehicles fitted with different engines require separate identification.

Nissan Navara D40

The D40 introduced a different vehicle platform and several YD25 engine variations.

Selected 2.5L common rail D40 applications use Denso reference 095000-6250.

The Nissan Pathfinder R51 shares relevant engine and fuel-system applications with the D40, which explains why these vehicles often appear together in injector catalogues.

Nevertheless, the exact reference depends on the vehicle and production specification.

Nissan Navara NP300/D23

The NP300/D23 introduced the 2.3L YS23 diesel engine family, associated with the Renault-derived M9T engine architecture.

Relevant Australian applications use Continental/VDO common rail injectors rather than the earlier Denso YD25 components.

An injector specified for a D22 or D40 YD25 engine is not a replacement for the D23 YS23 engine.

Denso 095000-6240: Nissan Navara D22 YD25

The Denso 095000-6240 injector is listed for selected Nissan Navara D22 2.5L YD25 common rail diesel applications.

DieselInjectors.com.au stocks this genuine Denso injector under SKU 095000-6240.

D22 injector part numbers

Australian specialist suppliers identify the following references in connection with this injector family:

Reference	Description
095000-6240	Denso injector reference
DCRI106240	Denso aftermarket catalogue reference
16600-VM00A	Nissan OEM reference
16600-VM01A	Nissan OEM reference
16600-VM00B / VM00C / VM00D	Related Nissan references

These references are found in specialist parts catalogues, but the exact approved replacement relationship should be verified against Nissan or Denso application information.

Does 095000-6240 fit every D22 YD25?

No.

The correct application depends on the vehicle's fuel injection system, production information and original equipment specification.

Australian suppliers identify this injector with particular D22 YD25 Euro 4 applications and publish supporting VIN ranges.

The year of registration alone is not sufficient to confirm fitment.

If the existing injector has a different number, check whether it is an approved equivalent rather than assuming every D22 YD25 uses the same component.

What does the DCRI number mean?

Denso uses DCRI numbers for certain aftermarket catalogue references.

These numbers are not injector correction codes.

The original Denso reference, Nissan OEM number and vehicle application should be checked together.

Denso 095000-6250: Nissan Navara D40 & Pathfinder R51

The Denso 095000-6250 injector is listed for selected Navara D40 and Pathfinder R51 vehicles using the 2.5L YD25 common rail diesel engine.

This is a different injector family from the D22 reference 095000-6240.

The fact that both vehicles use engines carrying the YD25 designation does not prove interchangeability.

D40 YD25 injector part numbers

Common Australian catalogue references include:

Reference	Description
095000-6250	Denso injector reference
DCRI106250	Denso aftermarket catalogue reference
16600-EC00A	Nissan OEM reference
16600-EC00B / EC00C / EC00D / EC00E	Related Nissan references
16600-EB70A / EB70B / EB70C / EB70D	Related Nissan references

These are useful identification references, but the correct replacement must still be confirmed for the individual vehicle.

What about 095000-6251 and other similar numbers?

Australian diesel specialists list additional references within the 095000-625 injector family.

However, not every numerically similar injector should automatically be treated as interchangeable.

Where the original injector number differs, confirm the manufacturer's approved part-number relationship before ordering.

The full Nissan OEM reference and VIN provide useful additional identification information.

Why do D40 and Pathfinder applications overlap?

The D40 Navara and R51 Pathfinder share certain 2.5L YD25 common rail engine applications.

As a result, some genuine Denso injector references are listed for both vehicles.

That does not mean every Pathfinder R51 or Navara D40 has the same injector.

Different engines, production dates and fuel-system variants require individual verification.

Thai-Built vs Spanish-Built Nissan Navara D40: Why It Matters

An important complication when purchasing D40 parts in Australia is that vehicles were manufactured at different production facilities.

Australian specialist catalogues distinguish Thai-built and Spanish-built vehicles using VIN information.

Common VIN prefixes include:

• MNT — associated with Thai-built Nissan applications.
• VSK — associated with Spanish-built Nissan applications.

These prefixes can help identify the correct vehicle specification.

However, a VIN prefix is only one part of the identification process.

Does country of manufacture change the injector?

It can affect which components and production specifications apply.

The D40 was manufactured across different plants and production periods, and parts catalogues include build-specific restrictions.

Country of manufacture should therefore be checked when identifying injectors and associated fitting components.

Why is this especially important for fitting kits?

DieselInjectors.com.au stocks a Nissan Navara D40 and Pathfinder R51 injector fitting kit under SKU ISK-YD25-D40.

The current listing identifies particular Spanish-built YD25 applications with VINs beginning VSK, including a specified production period.

This kit must not be described as suitable for every D40 simply because the engine is a YD25.

Check the VIN and product's complete application details before ordering.

Continental/VDO A2C3335190080: Nissan Navara NP300/D23

The Nissan NP300/D23 uses a different diesel engine family from the earlier D22 and D40 YD25 vehicles.

Selected 2.3L YS23 applications use Continental/VDO injector reference A2C3335190080.

DieselInjectors.com.au stocks this genuine VDO injector for relevant NP300/D23 applications.

NP300 injector part numbers

Australian specialist suppliers list:

Reference	Description
A2C3335190080	Continental/VDO injector reference
A2C33351900	Related catalogue reference
16600-00Q2K	Nissan OEM reference
16600-00Q2F / 16600-00Q2H	Related Nissan references
16600-0372R	Related OEM reference

The precise cross-reference and vehicle application must be confirmed before ordering.

What engine does the NP300 use?

Australian NP300/D23 diesel models include 2.3L four-cylinder engine variants commonly identified within the YS23 family.

You may encounter designations such as:

• YS23DDT.
• YS23DDTT.
• M9T.

These are associated with related engine configurations and specifications.

Do not assume every engine designation, power output or production period automatically uses an identical injector.

Is A2C3335190080 a piezo injector?

The Continental/VDO injector family is associated with piezoelectric common rail technology.

A piezo injector uses an electrical actuator with different operating characteristics from a conventional solenoid injector.

The technology is part of the injection-system design.

It does not mean the injector can be fitted to another common rail engine simply because the electrical connector or mounting arrangement appears similar.

Why might the injector be advertised as Siemens or Schaeffler?

You may encounter the names Siemens VDO, Continental, VDO, Vitesco or Schaeffler when researching some diesel injection components.

These names reflect the history and changing ownership or branding of automotive component businesses.

However, brand names alone do not prove two products are identical.

The manufacturer reference and approved vehicle application remain the important identification details.

Can You Swap D22, D40 and NP300 Injectors?

No direct interchangeability should be assumed.

The different Navara generations use different injector specifications and, in some cases, different fuel injection manufacturers.

For example:

• Denso 095000-6240 is listed for selected D22 YD25 applications.
• Denso 095000-6250 is listed for selected D40 YD25 and Pathfinder R51 applications.
• Continental/VDO A2C3335190080 is listed for selected NP300/D23 2.3L applications.

These are separate components.

Even two Denso injectors from the YD25 family should not be substituted without confirming their exact specifications.

An injector may fit physically but still have incompatible internal characteristics or ECU calibration requirements.

Use the correct OEM reference or an officially approved supersession.

Common Nissan Navara Diesel Injector Problems

Diesel injector faults can affect starting, idle quality, engine power and combustion.

Common symptoms that may justify further investigation include:

• Rough or unstable idle.
• Hard starting or extended cranking.
• Increased diesel knock.
• Excessive exhaust smoke.
• Hesitation or loss of power.
• Increased fuel consumption.
• Relevant fuel-system fault codes.

These symptoms do not prove that an injector is faulty.

The same problems can arise from fuel supply, pressure-control, electrical or mechanical faults.

Hard starting on a YD25

Excessive internal injector leakage can prevent the common rail from reaching the required pressure during cranking.

However, a faulty fuel metering component, inadequate supply pressure, high-pressure pump problem or another fault may produce similar symptoms.

The correct repair depends on diagnosis.

Rough idle or knocking

Poor injection control can cause uneven combustion and increased noise.

But engine noise must not automatically be attributed to injector wear.

A technician may need to investigate the injection system, fuel quality, engine mechanical condition and relevant control components.

Black smoke and reduced power

Incorrect fuel delivery can contribute to excessive smoke or poor running.

Other causes include air-system restrictions, turbocharger faults, EGR problems, boost-control issues and engine mechanical problems.

Replacing injectors without establishing the actual cause can be expensive and ineffective.

Fuel contamination

Precision injector components can be damaged by water, dirt or metallic debris.

If contamination originates from a damaged high-pressure pump, the repair may involve other affected fuel-system components.

Installing new injectors into a contaminated system can lead to further failures.

How Are Nissan Navara Diesel Injectors Tested?

The appropriate testing process depends on the engine and suspected fault.

Diagnostic fault codes and live data

A technician may examine fault codes and relevant operating information, including commanded versus actual fuel rail pressure and applicable injector correction values.

This information helps identify possible faults but does not provide a complete assessment of injector condition.

Return-flow testing

A controlled injector return-flow test can help diagnose excessive internal leakage on suitable common rail systems.

However, a normal return-flow result does not prove that an injector's spray pattern, fuel delivery or electrical characteristics are correct.

Specialist bench testing

A compatible injector test bench may be used to measure operating characteristics against the appropriate specification.

The test equipment and procedure must suit the particular Denso or Continental/VDO injector design.

Wider system diagnosis

The technician may also need to investigate fuel quality, filtration, high-pressure pump condition, pressure-control components and electrical circuits.

The objective is to identify the actual problem before replacing components.

For Brisbane customers, DieselInjectors.com.au provides access to specialist diagnostic and workshop assistance through its Geebung operation.

Enquire About Diesel Injector Testing

Should You Replace One Nissan Navara Injector or All Four?

The correct decision depends on the diagnosis.

A single-injector replacement may be appropriate where one component is confirmed faulty and the remaining injectors are operating within specification.

Replacing multiple injectors may be justified when testing confirms several failures or when contamination has affected the system.

Does high mileage mean all injectors need replacing?

Not necessarily.

Mileage and service history provide useful context, but they do not establish injector condition on their own.

An injector should be assessed according to its actual performance and the vehicle's repair requirements.

What if the high-pressure pump has failed?

A damaged pump may contaminate the fuel system with metallic debris.

In that situation, replacing injectors without addressing the pump and other contaminated components may cause repeat failures.

The affected fuel system needs assessment according to the manufacturer's repair procedure.

Do Nissan Navara Diesel Injectors Need Coding?

Many modern Nissan common rail diesel systems use injector compensation or correction information.

The requirements differ between YD25 Denso systems and later Continental/VDO applications.

D22 and D40 YD25 coding

Relevant Denso-equipped YD25 applications may require injector compensation data to be entered into the engine control unit after replacement.

The correct procedure depends on the engine and ECU generation.

A genuine replacement injector does not automatically eliminate the coding requirement.

NP300/D23 coding

The Continental/VDO injector must be installed and commissioned according to the vehicle's specified procedure.

The technician must confirm the appropriate injector calibration information, diagnostic equipment and any additional ECU learning requirements.

Is coding the same as injector testing?

No.

Testing evaluates injector condition or performance.

Coding registers calibration information with the engine management system where required.

Coding cannot repair internal wear, electrical failure or contamination.

For more information, read our diesel injector coding guide.

What Other Parts Are Needed When Replacing Navara Injectors?

Injector replacement may involve more than the injector itself.

Depending on the engine and manufacturer's procedure, the repair can require:

• Injector combustion sealing washers.
• Injector body O-rings and oil seals.
• Rocker cover gaskets.
• Injector retaining components.
• High-pressure fuel pipes.
• Return-line fittings and seals.
• Fuel filtration and contamination-related repairs.

Nissan Navara D40 fitting kit

DieselInjectors.com.au stocks an injector fitting kit for selected D40 Navara and Pathfinder R51 YD25 applications.

The kit contains components such as the rocker cover gasket, injector body O-rings, oil seals and leak-off gaskets.

Its fitment is restricted to specific applications.

Browse Injector Fitting Kits

High-pressure fuel lines

Common rail injector pipes operate under extremely high pressure.

The relevant service procedure determines whether particular pipes must be replaced after removal.

Never assume a high-pressure pipe is reusable simply because it looks undamaged.

Injector sealing components

Incorrect sealing or installation can lead to combustion leakage, fuel leakage or other problems.

The correct parts and tightening procedures depend on the engine.

Fuel contamination and filtration

If an injector has failed because of contaminated fuel or pump damage, the repair may require work beyond the injectors.

The underlying cause must be addressed before fitting replacement components.

How to Find the Correct Navara Injector Before Ordering

Before buying, follow these steps.

1. Confirm the vehicle generation

Identify whether your vehicle is a D22, D40 or NP300/D23.

If you have a Pathfinder, confirm its model and engine independently.

2. Identify the engine

Record the engine code and capacity.

A 2.5L YD25 and 2.3L YS23 are different engine families.

3. Record the original injector number

Use the manufacturer's part number or confirmed OEM reference.

Do not confuse the part number with the calibration or serial number.

4. Check the VIN and build information

The VIN helps identify the vehicle's original parts specification.

This can be particularly useful when dealing with D40 production variations and fitting-kit restrictions.

5. Verify the approved replacement

If a supplier lists an alternative or superseded part number, confirm that the relationship is valid for your specific application.

6. Confirm fitting and coding requirements

Establish which seals, lines, fasteners and calibration procedures the repair requires.

If the information remains uncertain, ask for a compatibility check before ordering.

Our diesel injector part-number guide explains the identification process in more detail.

Nissan Navara Diesel Injector FAQs

Do D22 and D40 Navaras use the same injectors?
