General Information

Component Location





General Description

The Electronic Throttle Control (ETC) system is made of the components throttle body, Throttle Position Sensor (TPS) 1 & 2 and Accelerator Position Sensor (APS) 1 & 2. The APS is mounted in the accelerator pedal to detect the opening angle of the accelerator pedal. It has 2 sensors to detect the accelerator position and a malfunction of the accelerator position sensor. The PCM judges the current opening angle of the accelerator pedal from APS 1 & 2, and the PCM controls the throttle motor based on these signals.

DTC Description

Checking output signals from APS 2, under detecting condition, if output signals are above the threshold, PCM sets P2128 and then MIL (Malfunction Indication Lamp) turns on.
