Problem overview

Some Kia Amanti owners report experiencing stalling issues after replacing the accelerator pedal position sensor, which may indicate a faulty installation or related problems with the sensor. These owners note that the accelerator pedal position sensor is crucial for the connection between the driver and the vehicle's ECU, and improper installation can lead to stalling. Common symptoms of a malfunctioning sensor include an unresponsive accelerator pedal, a check engine light, shifting issues, rough idling, and increased fuel consumption. Proper diagnosis and repair of the sensor are essential to prevent rough idling and inconsistent acceleration. If stalling occurs post-replacement, it is advised to recheck the installation, repair any faulty connections, or consider replacing the sensor again if necessary.
