DESCRIPTION
DTC Detection Condition:
The accelerator pedal position sensor is mounted on the accelerator pedal to detect how much the pedal is depressed. This is a non-contact sensor with hall elements. It has 2 sensors per sensor unit. One is used to detect the accelerator pedal position and the other to detect a malfunction in the sensor itself. In the accelerator pedal position sensor, the voltage applied to terminals VPA1 and VPA2 of the HV control ECU varies between 0 and 5 V in accordance with the accelerator pedal position. Terminal VPA2 is used to detect a malfunction in the sensor itself. The HV control ECU determines the current accelerator pedal position and controls the hybrid control system based on signals received from terminals VPA1 and VPA2.
