Parts for your 2006 Nissan Navara-Throttle position sensors

2006 Nissan Navara throttle position sensor: is it fitted and what does it do?

Yes, the 2006 Nissan Navara uses a throttle position sensor (TPS). Technical references back this up: the Nissan Navara D40 Factory Service Manual (EC – Engine Control, VQ40DE petrol, EC – Engine Control, YD25DDTi diesel) describes throttle angle feedback to the ECM via TPS signals. On the VQ40DE petrol, the TPS is built into the electronic throttle body (with dual sensors for redundancy). On the YD25DDTi diesel, there’s an intake throttle/air control valve used for EGR control and smooth shutdown, and that valve has a position sensor. Nissan’s FAST electronic parts catalogue also lists these components as assemblies containing a position sensor.

On this model, the TPS tells the engine computer how far the throttle plate has moved. In the petrol VQ40DE, it’s critical for managing drive-by-wire throttle response, fuelling and idle speed. In the YD25 diesel, the position sensor confirms the commanded angle of the intake throttle used for EGR flow and engine shutdown smoothness, helping avoid shudder on key-off.

If the sensor signal goes wonky, the ute may feel doughy off the line, surge or hunt at idle, drop into limp mode, or light the MIL. Common DTCs include P0120–P0124 and P0220–P0229. Before swapping parts, it’s worth checking the connector for corrosion, damaged pins, or chafed wiring near the throttle body/intake valve and across the front of the engine bay.

Servicing tips for Aussie and Kiwi owners:

• Petrol VQ40DE: the TPS is integrated into the throttle body, so replacement usually means a complete throttle body. After fitting, perform a throttle closed-position and idle-air volume learn with a scan tool, or follow the service manual’s pedal/ignition procedure. Keep the plate clean with proper throttle cleaner—don’t drown the motor or sensors.
• Diesel YD25DDTi: the intake throttle/air control valve is typically serviced as an assembly. Look for oil mist build-up from the PCV and EGR—clean lightly without forcing the plate. After replacement, carry out the ECM learn procedure and clear codes. A scan of live data (APP vs throttle angle) is handy to confirm operation.

As a rule of thumb, inspect electrical connectors and harness routing every 20,000–30,000 kilometres, especially if the vehicle sees corrugations or water crossings. Always disconnect the battery before unplugging throttle components, and use a torque wrench on mounting fasteners to avoid warping housings.

Does a 2006 Nissan Navara have a throttle position sensor?

It does. On the VQ40DE petrol it’s integrated into the electronic throttle body. On the YD25DDTi diesel it’s part of the intake throttle/air control valve used for EGR and smooth shutdown. Both report throttle angle back to the ECM.

What symptoms point to a failing TPS on a Navara D40?

Hesitation, inconsistent throttle response, high or hunting idle, stalling when coming to a stop, and limp mode are common. You may see codes like P0120–P0124 or P0220–P0229. Always check connectors and wiring before condemning the unit.

Do I need a relearn after replacing the throttle body or intake throttle valve?

Yes. Perform throttle closed-position and idle-air volume learning with a proper scan tool or the manual learn routine from the factory service manual. Without this, idle quality and throttle response can be ordinary until the ECM adapts.
