The accelerator pedal position sensor measures how far the driver presses the accelerator, sending this signal to the ECU on electronic (drive-by-wire) throttle systems.
If you notice any of the following, the part likely needs replacement:
Hesitation or inconsistent throttle response
Check Engine light with an accelerator pedal fault code
Engine going into limp mode (reduced power)
Installation information
Integrated into the accelerator pedal assembly — a throttle relearn procedure is often required after installation.
Frequently asked questions
The ECU needs to record the exact minimum and maximum positions of the new sensor to accurately translate accelerator pedal input into throttle movement.

I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
