Parts for your 2013 Nissan Navara-Throttle position sensors

2013 Nissan Navara throttle position sensors (TPS) — what they do and how to look after them

Based on factory technical literature, the 2013 Nissan Navara (D40) does use throttle position sensing. The petrol VQ40DE runs an electronic throttle control actuator with an integrated throttle position sensor, it isn’t serviceable separately from the throttle body (Nissan Navara D40 Service Manual, EC section: Electronic Throttle Control). The YD25DDTi and V9X diesels use an intake throttle valve (often called throttle control valve) with a built‑in position sensor, plus an accelerator pedal position sensor, again, the position sensor is integral to the unit (ESM D40, Engine Control/Intake Air sections). These sources confirm a TPS function is present, though typically combined with the throttle body/valve rather than a stand‑alone part.

On the Navara, the TPS lets the engine control module know exactly how far the throttle plate is open. That data is blended with inputs from the MAF, MAP, O2 and pedal sensors to manage torque, idle stability, emissions and transmission shift timing. If the reading is dodgy, the ute can feel doughy off the line, surge, idle rough, or drop into limp mode, often popping codes like P0120–P0123, P2119 or P2101.

Servicing is straightforward but a bit different depending on engine:

• Petrol VQ40DE: the TPS is integral to the throttle body. If the sensor fails, the fix is usually replacing the complete throttle body. After refit, perform throttle closed‑position and idle air volume learning with a scan tool, and clear codes.
• Diesel YD25/V9X: the intake throttle valve can soot up and stick, skewing position feedback. Cleaning the valve bore and plate with diesel‑safe cleaner can restore operation. If the position sensor is faulty, replace the valve assembly. Run an ECM relearn if specified and check for updated calibrations.

General tips the workshop will follow:

1. Scan for codes and live data, compare commanded vs actual throttle angle and pedal position.
2. Inspect the connector and loom near the throttle body/valve for oil ingress or broken wires.
3. Clean the throttle plate (petrol) or intake throttle valve (diesel) if sticking is evident.
4. Replace the assembly if the sensor fails range/performance tests, use OE‑quality parts.
5. Complete throttle/idle learn procedures and road‑test under load.

Backed by Nissan’s ESM references for the D40 platform, the takeaway is simple: yes, the 2013 Navara relies on throttle position sensing, and keeping the throttle body/valve clean, the wiring sound, and relearns up to date will keep it crisp and compliant with Aussie and Kiwi conditions.

FAQs

Does a 2013 Navara have a separate TPS I can swap on its own?
On most 2013 D40s, no. The TPS is built into the electronic throttle body (petrol) or the intake throttle valve (diesel). If the sensor fails, the usual remedy is replacing the whole assembly. The accelerator pedal also has its own position sensor, which is a separate part.

What are the common signs of a failing TPS on a 2013 Navara?
Expect hesitant acceleration, hunting idle, poor fuel economy, cruise control drop‑outs, and a check engine light. Scan tools commonly show mismatch between commanded and actual throttle angle, and may log P0120–P0123 or throttle actuator control codes. On diesels, a sticking intake throttle from soot can mimic TPS faults.

Do I need to calibrate anything after replacing the throttle body or valve?
Yes. Perform throttle closed‑position and idle air volume learning with a capable scan tool. Battery resets alone are hit‑and‑miss. This step helps avoid high idle, stalling or sluggish response after the repair.
