This throttle position sensor replaces Mitsubishi OEM part MD628077, delivering precise throttle-angle data to the ECU on Pajero and Triton four-wheel drives and on Chrysler PT Cruiser and Sebring models fitted with the 2.4L EDZ engine. Direct-connector replacement — same 3-pin rectangular housing, same anticlockwise rotation, same calibration range as the original Mitsubishi unit.

A worn or failed TPS sends incorrect voltage signals that leave the ECU unable to accurately read throttle position. On the Pajero under trail conditions or the Triton under a heavy tow load, this shows as hesitation, power surge, and erratic shifting at exactly the moment you need smooth, predictable response. Replacing the sensor early restores full ECU authority over fuelling and transmission control.

FITMENT CHECK

The Pajero NM was produced in both DOHC (149kW) and SOHC (140kW) configurations — OEM part MD628077 is shared across both, and this sensor fits both. The Triton ML MN 4G64 was produced in 94kW and 97kW output variants; both are covered here. Chrysler PT Cruiser and Sebring fitment covers the 2.4L EDZ petrol engine only — diesel and turbo variants are not applicable.

ABOUT THIS SENSOR

3-pin rectangular connector. Anticlockwise rotation. Supplied without cable. The resistance sweep across the throttle range matches the OEM MD628077 calibration, so the ECU reads no difference on first start. Built to withstand the heat cycling and vibration exposure typical of 4WD engine bays — Pajero V6 bay temperatures and Triton towing duty included.

COMMON SYMPTOMS OF FAILURE

Rough or hunting idle that varies with throttle movement
Hesitation or flat spot when pulling away from rest
Surge at steady highway speed
Unexplained drop in fuel economy
Automatic transmission shifting at incorrect points or hunting between gears
Check engine light — fault codes P0121, P0122, P0123

What fault codes does a faulty TPS trigger?

A faulty throttle position sensor typically triggers codes P0120 to P0124. P0120 and P0121 indicate the TPS signal is out of range, P0122 and P0123 indicate the signal is too low or too high, and P0124 indicates an intermittent signal. On drive-by-wire vehicles additional codes related to the electronic throttle control system may also be present.

Can a faulty TPS cause my automatic transmission to shift incorrectly?

Yes. The ECU shares throttle position data with the transmission control module to determine when to upshift and downshift. A faulty TPS sending incorrect throttle angle data can cause erratic shift points, harsh gear changes, the transmission hunting between gears, or the vehicle remaining in a fixed gear. Replacing the TPS often resolves transmission behaviour issues that appear unrelated.

Is it safe to drive with a faulty throttle position sensor?

It depends on how severely the sensor has failed. A partially failed TPS may cause hesitation and poor throttle response but the vehicle remains driveable. A fully failed TPS on a drive-by-wire vehicle can trigger limp mode, restricting the engine to a fixed low throttle position to prevent runaway acceleration. In either case replace the sensor as soon as possible as the fault can worsen without warning.

What are the symptoms of a faulty throttle position sensor?

Symptoms include jerky or hesitant acceleration, rough idle, unexpected surging, poor throttle response, stalling, and fault codes P0120-P0124. Drive-by-wire vehicles may also enter a limp mode limiting engine power.

Can I clean a throttle position sensor instead of replacing it?

TPS sensors are sealed units and cannot be cleaned or adjusted reliably. If the sensor is producing erratic signals or fault codes, replacement is the correct solution. Attempting to clean or adjust it usually results in continued faults.

Do I need to calibrate the throttle position sensor after replacement?

Many vehicles require a TPS calibration or throttle body relearn procedure after replacement. This is usually done with an OBD2 scanner or by following a specific ignition on/off sequence. Check your vehicle's service manual or contact us for guidance.
