This throttle position sensor is a direct-fit replacement for the Toyota Coaster RZB40 and RZB50 bus, Dyna 200 and 300 truck, Granvia RCH11W, and HiAce H100 and H40, all fitted with the 3RZ-FE 2.7L four-cylinder or 5VZ-FE 3.4L V6 petrol engine. It replaces OEM numbers 89452-35020 and 89452-35100 - same 3-pin rectangular housing and anticlockwise rotation as the original unit.

These are workhorse commercial platforms - a bus route, a delivery run, a loaded van - where an inaccurate throttle signal costs fuel and reliability every single day. Replacing a worn TPS restores accurate fuelling and smooth power delivery under continuous duty.

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.
