Parts for your 2011 Nissan Navara-Throttle position sensors

2011 Nissan Navara throttle-position-sensors: what they do and when to service them

Based on the Nissan D40 Navara Factory Service Manual (2010–2012 editions) and dealer service procedures, the 2011 Nissan Navara is fitted with throttle-position-sensors (TPS). On petrol variants (QR25DE/VQ40DE), the TPS is built into the electronic throttle body as dual tracks for redundancy. On diesel variants (YD25DDTi/V9X), the intake throttle control valve (used for EGR modulation and smooth shutdown) has an internal position sensor. The accelerator pedal also uses a separate pedal position sensor. So, yes—TPS is relevant and used on 2011 Navara models.

The TPS tells the engine control module how far the throttle plate (or diesel throttle valve) is open. That input is crucial for fuel delivery, ignition timing, EGR operation, cruise control and, on autos, shift quality. When the sensor goes out of whack, drivers may notice rough idle, flat spots, stalling at junctions, limp-home behaviour, or codes like P0120–P0123, P2135 and friends. Because the Navara’s TPS is typically integrated, it’s usually the whole throttle body (petrol) or throttle control valve (diesel) that gets replaced, rather than the sensor by itself.

As part of regular servicing of your 2011 Nissan Navara throttle-position-sensors, the smart play is preventative care. For petrol engines, a periodic clean of the throttle body every 60,000–100,000 km with proper throttle-body cleaner (not carb cleaner) helps keep the blade from sticking and preserves accurate sensor readings. Don’t force the butterfly by hand—use the scan tool test where possible. For diesels, check the throttle control valve for oil mist build-up and make sure the connector and loom aren’t chafed near the intake.

If replacement’s on the cards, budget for a new gasket and plan on doing the factory relearn. After fitting, perform Throttle Valve Closed Position and Idle Air Volume Learn (often via CONSULT-III Plus or a manual pedal/ignition sequence). Skipping this can leave the idle high, low, or hunting. Check live data to confirm the accelerator pedal position agrees with TPS tracking, and clear codes. A quick road test under light and moderate throttle seals the deal.

Handy note for DIYers: many aftermarket “TPS-only” listings don’t suit the 2011 Navara because the sensor is integrated. If the part bolts to the throttle body or valve on its own, double-check fitment before buying.

Popular questions

Does a 2011 Nissan Navara actually have a TPS?
Yes. Petrol models use an electronic throttle body with dual built-in TPS tracks, and diesel models use a throttle control valve with a position sensor. There’s also a separate accelerator pedal position sensor, which is different to the TPS.

Can the TPS be replaced on its own, or is it part of the throttle body?
On most 2011 Navaras it’s integrated. That means replacing the full throttle body (petrol) or the throttle control valve (diesel). Standalone TPS units usually don’t fit these electronic assemblies.

What fault codes point to a TPS problem on a 2011 Navara?
Common ones include P0120–P0123 (TPS circuit range/performance), P2135 (throttle/pedal position sensor correlation) and related ETC codes. Always confirm with live data and wiring checks before replacing parts.
