Where is the throttle valve position sensor located on the Audi Q3?

Model: Audi Q3 8U - Years 2011-2018
Part: Checks and maintenance

In this video we see where the TPS position sensor is located on the Audi Q3: it is right on the throttle valve, connected to the end of the throttle shaft, on the intake manifold (so near the engine) and electronically connected to the ECU and mechanically to the accelerator pedal. The symptoms of a faulty TPS are the check engine light on, a reduction in power, irregular acceleration, and problems with the start & stop. To perform the operation we will need a T20 star screwdriver, a 10mm wrench, a flathead screwdriver, and an OBD2 scanner. Let's start by disconnecting the battery, removing the electrical connector of the TPS, removing the sensor by unscrewing the two 10mm bolts and rotating the sensor to disconnect it from the alignment metal pins. Install the new sensor that we would have purchased for example on ovoko. It with the code glp365-5q0907651 at a price of 20.00 euros + 14.48 euros for shipping. Reconnect the sensor, making sure the red clip is locked, and then reset the error using an OBD2 scanner to clear the error. Take this opportunity to clean the throttle body; some models require calibration for throttle relearning, which can also be done with the diagnostic tool. Before proceeding with this operation, it is advisable to check the fuses, as a blown fuse can cause the same symptoms as a faulty TPS.
