Parts for your 2006 Mitsubishi Pajero-Throttle position sensors

2006 Mitsubishi Pajero throttle-position-sensors (TPS)

Yes, throttle-position-sensors are relevant and used on the 2006 Mitsubishi Pajero. Technical references from Mitsubishi’s factory workshop manuals and wiring diagrams for the NS-generation Pajero (covering the 2006 model year) show the 3.8L V6 petrol (6G75) uses electronic throttle control with dual TPS tracks built into the throttle body, and the 3.2L Di‑D diesel (4M41) uses an electronically controlled throttle valve for EGR/shutdown that includes a position sensor, alongside an accelerator pedal position sensor. This is consistent with MUT‑III diagnostic procedures and OBD‑II fault coverage (e.g., TPS correlation codes such as P0120–P0123, P2135) documented for these engines in Mitsubishi service literature.

On a 2006 Pajero, the throttle-position-sensor tells the engine computer exactly how far the throttle blade is open. On the petrol V6, it’s integral to the throttle body and works with the drive‑by‑wire motor to deliver smooth response, stable idle and proper shift timing. On the Di‑D diesel, the throttle valve isn’t for engine load like petrol, but the position sensor still matters for EGR control, smoother shutdown and emissions.

When the TPS goes off, owners may notice lazy throttle response, hunting idle, sudden limp mode, or the check engine light. Because the sensor is built into assemblies on many variants, “replacement” often means fitting a complete throttle body (petrol) or throttle valve unit (diesel). There’s no scheduled replacement interval in the service books, but inspection during regular servicing is smart, especially on high‑kilometre vehicles or those used off‑road.

• Keep the throttle body clean on the petrol 6G75. Use throttle‑body cleaner sparingly, avoiding direct spray into the sensor housing.
• Check the connector and loom for corrosion or broken wires. A dab of dielectric grease on reassembly can help in wet conditions.
• Scan live data. Both TPS tracks should move smoothly and agree with accelerator input, dropouts or mismatch point to trouble.
• If replaced, carry out throttle/idle relearn with a capable scan tool. Diesel throttle valve replacement may also require adaptation.

DIYers should disconnect the battery before unplugging the throttle body or throttle valve, and never force the throttle plate by hand on the drive‑by‑wire units. If faults persist after cleaning and relearn, a full assembly swap is often the most reliable fix. Using quality parts and following the workshop manual procedures will keep the Pajero’s response crisp and its emissions gear happy.

Popular questions about 2006 Mitsubishi Pajero throttle-position-sensors

Does the 2006 Pajero diesel actually have a TPS?
Yes. While the 4M41 diesel doesn’t use a throttle to control engine load, it does have an electronically controlled throttle valve with a position sensor for EGR flow management and smooth shutdown. You’ll also find an accelerator pedal position sensor that works with the ECU for drive‑by‑wire control.

What are the signs a TPS is failing on a 2006 Pajero?
Common clues include erratic idle, flat spots on acceleration, surging, poor economy, and the check engine light. Scanning may show TPS correlation or range/performance codes. If live data shows dead spots as the pedal is moved, the sensor or its wiring is suspect.

Do I need to calibrate or relearn the TPS after replacement?
Usually, yes. The petrol V6 throttle body and the diesel throttle valve often need an idle/throttle relearn with a suitable scan tool. Skipping this step can leave the idle unstable or trigger fault codes even if the hardware is fine.
