This throttle position sensor is a direct-fit replacement for Toyota Hilux RZN149, RZN154, RZN169 and RZN174 with the 2.7L 3RZ-FE engine, and for Hilux VZN1 with the 3.4L V6 5VZ-FE engine. It replaces OEM numbers 89452-35020 and 89452-35100 - same 3-pin rectangular housing, same anticlockwise rotation, same resistance sweep as the original unit.

A worn TPS on a working Hilux shows up exactly when you can't afford it - hesitation pulling a trailer, surge at highway speed, or an automatic transmission that can't decide what gear to hold. Replacing the sensor early keeps the fuelling and transmission mapping accurate under load.

TO SUIT

This sensor fits the Toyota Hilux RZN149 and RZN154 Platform/Chassis and Ute variants with the 2.7L 3RZ-FE engine (08/97 - 08/05), the RZN169 and RZN174 4WD Ute with the same 3RZ-FE engine (11/97 - 10/02), and the Hilux VZN1 Ute with the 3.4L V6 5VZ-FE engine (08/01 - 07/05).

FITMENT CHECK

This listing covers the RZN and VZN1 Hilux variants only - the 4WD V6 VZN167 and VZN172 utility is covered by a separate listing. Diesel Hilux variants (KZN, LN) do not use this sensor. Replaces OEM numbers 89452-35020 and 89452-35100.

ABOUT THIS SENSOR

3-pin rectangular connector. Anticlockwise rotation. Supplied without cable. 2 mounting bores. Calibrated to the OEM resistance specification for Toyota 89452-35020 across both the 3RZ-FE four-cylinder and 5VZ-FE V6 throttle sweep.

These RZN and VZN1 Hilux utes are commonly run as tradie and farm workhorses, where a steady, predictable throttle response under a heavy load matters more than outright performance - exactly what an accurate TPS signal delivers.

COMMON SYMPTOMS OF FAILURE

Rough or hunting idle, especially when the engine is warm
Hesitation or stumble when pulling away from a standing start
Surge at constant highway speed
Unexplained increase in fuel consumption
Automatic transmission shifting at incorrect points
Check engine light - fault codes P0120, P0121, P0122, P0123

[08/97 - 08/05] TOYOTA HILUX RZN149/ RZN154 2.7L 4cyl 3RZ-FE 107kW
[11/97 - 10/02] TOYOTA HILUX RZN169/ RZN174 2.7L 4cyl 3RZ-FE 108kW
[08/01 - 07/05] TOYOTA HILUX VZN1 3.4L V6 5VZ-FE 131kW

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.
