This throttle position sensor replaces Toyota OEM part 89452-35020, restoring accurate throttle position data to the ECU on Land Cruiser Prado RZJ90 and RZJ95 series with the 2.7L 3RZ-FE engine, and on Prado RZJ120 and RZJ125 series. Direct-connector replacement — same 3-pin rectangular housing and anticlockwise rotation as the original Toyota unit.

The Prado is often loaded with camping gear, towed with a trailer, or used across rough terrain where steady and predictable throttle response is non-negotiable. A worn TPS causes the ECU to misread throttle angle, producing unexpected hesitation under load or surge during steady-speed driving. Replacing the sensor early eliminates the problem and restores the confident, linear response these vehicles are built for.

FITMENT CHECK

This listing covers the 2.7L 3RZ-FE petrol Prado RZJ series only. The V6 5VZ-FE Prado (VZJ90 VZJ95) is covered by a separate listing. Diesel Prado variants (1KZ-TE, 1HD-FTE) do not use this sensor. Replaces OEM numbers 89452-35020 and 89452-35100.

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.
