Parts for your 2007 Nissan Navara-Throttle position sensors

2007 Nissan Navara throttle-position-sensors — what they do and how to look after them

Technical references confirm the 2007 Nissan Navara does use a throttle position sensor (TPS). The Nissan Factory Service Manual (D40 ESM, EC section) details an Electronic Throttle Control with an integrated TPS on the VQ40DE petrol, and a throttle control valve (intake air control/throttle plate) with a built‑in position sensor on the YD25DDTi diesel. Nissan’s FAST parts catalogue lists the throttle body/throttle control valve assemblies with the sensor integrated, and workshop databases such as Autodata note the TPS is non‑serviceable separately on many variants. So yes, a TPS is fitted — it’s just typically part of the throttle body or throttle control valve assembly rather than a stand‑alone bolt‑on sensor.

On a 2007 Navara, the TPS tells the engine control module exactly how far the throttle is open. On the petrol VQ40DE, it’s the heart of the drive‑by‑wire system, giving smooth response and stable idle. On the YD25 diesel, the throttle plate isn’t for normal air metering like a petrol, instead, its position helps EGR flow and clean shutdowns, so that position feedback still matters for emissions, drivability and stall‑free stops.

As part of routine servicing of a 2007 Navara, it’s smart to keep the TPS and its hardware happy. While the sensor itself is sealed inside the throttle body or throttle control valve, a few checks go a long way:

• Scan for fault codes (P0120–P0123, P2135, etc.) and check live data for steady throttle angle readings with a smooth sweep.
• Inspect the connector under the bonnet for corrosion, broken locks or oil ingress, clean with proper contact cleaner.
• On YD25 diesels, check for soot buildup in the throttle control valve and EGR plumbing, gentle cleaning can restore smooth operation. Avoid forcing the butterfly by hand.
• If the assembly is replaced, carry out throttle and accelerator pedal relearn procedures (closed position and idle learn) using a scan tool or the specified learn sequence.

Replacement is usually of the whole throttle body (petrol) or throttle control valve (diesel). Use a new gasket, torque fixings correctly, and don’t pinch the wiring. After fitting, confirm there are no air leaks, perform the relearn, and road‑test for clean tip‑in and stable idle. Done right, the ute will feel crisp and predictable, and fuel use and emissions will stay on song for many more kilometres.

Does a 2007 Navara actually have a throttle position sensor?

Yes. Factory documentation for both the D40 petrol and YD25 diesel shows a TPS integrated into the throttle body (petrol) or throttle control valve (diesel). It’s not usually a separate sensor you can swap on its own.

What are common signs the TPS/throttle control valve is playing up?

Drivers might notice erratic idle, flat spots on light throttle, cruise control dropping out, limp mode, or the MIL on with codes like P0120–P0123 or P2135. On diesels, rough shutdown or harsh EGR transitions can also point to issues.

Do I need to calibrate anything after replacing the throttle body or valve?

Yes. Perform the throttle closed‑position and idle/air volume learn, and the accelerator pedal released‑position learn. A capable scan tool makes this straightforward, doing it prevents high idle, poor response, and repeat fault codes.
