Parts for your 2014 Toyota Rav4-Throttle position sensors

2014 Toyota RAV4 Throttle Position Sensor (TPS)

Based on technical sources including the Toyota Repair Manual (via Toyota Technical Information System), the Engine Control System documentation for the 2014 RAV4 (petrol 2AR‑FE and diesel variants) and Toyota’s Electrical Wiring Diagram, this model uses Electronic Throttle Control (ETCS‑i). The throttle position is monitored by sensors built into the electronic throttle body (commonly referenced as TP/TPS signals such as VTA1/VTA2). There’s also an accelerator pedal position sensor at the pedal. The TPS is therefore absolutely relevant to a 2014 RAV4, but it’s integrated into the throttle body and isn’t serviced as a separate bolt‑on sensor.

The throttle position sensor in a 2014 RAV4 tells the engine control module exactly how far the throttle plate is open. That live signal is crucial for smooth acceleration, stable idle, fuel delivery, ignition timing, transmission shift quality, cruise control, traction and stability control. Because this RAV4 runs ETCS‑i, the ECM commands a small electric motor to move the throttle plate and constantly cross‑checks two internal TPS tracks for accuracy. If the signals disagree, it throws a fault and can drop the vehicle into limp mode to protect the engine and driveline.

When the TPS circuit plays up, it often shows up as a check engine light, sluggish response, surging, high or hunting idle, poor fuel economy or harsh shifting. Common fault codes technicians see on these include P0120–P0124 (TPS range/performance or circuit) and P2135 (TPS correlation), among others noted in Toyota’s diagnostic charts.

As part of regular servicing, it’s worth checking live data with a scan tool to confirm stable throttle angle readings and good correlation with the accelerator pedal sensors. Keeping the throttle body clean helps too: remove the intake duct and gently clean the bore and plate with a throttle‑safe cleaner, avoiding harsh scrubbing of the factory coating. Don’t force the plate open by hand—use the scan tool’s active test or gently open it only as needed.

If the TPS is faulty, the fix on this model is to replace the complete throttle body assembly (the sensor isn’t designed to be replaced separately). Fit a new gasket, inspect the loom and connector for damage, then perform the idle/throttle relearn—either with a capable scan tool or by following the repair manual’s procedure (key‑on initialisation and warm‑up without touching the accelerator). Sticking to factory torque specs and procedures keeps things sweet and avoids repeat faults.

Does a 2014 RAV4 actually have a throttle position sensor?

Yes. Toyota’s ETCS‑i uses dual throttle position signals built into the electronic throttle body. It isn’t a separate screw‑on sensor like older models, but it does the same job—only more accurately and with built‑in redundancy.

Can the TPS be replaced on its own, or do you need a new throttle body?

On the 2014 RAV4, the TPS is integrated into the throttle body and isn’t serviced separately. If the sensor fails testing per the repair manual, the recommended repair is a complete throttle body replacement with a new gasket, followed by a relearn.

Is any programming needed after fitting a new throttle body?

A formal “programming” isn’t usually required, but a throttle/idle learn is. Many scan tools can run the ETCS initialisation, otherwise follow the manual’s key‑on and warm‑up procedure. Make sure there are no air leaks and the throttle plate isn’t held open by carbon build‑up.
