Accelerator Pedal (AP) Sensor

Accelerator Pedal (AP) Sensor:

DESCRIPTION
The Accelerator Pedal (AP) Sensor is mounted on the accelerator pedal and detects the position of the accelerator pedal.

OPERATION
The accelerator pedal position information is sent as a voltage signal to the PCM. The PCM uses this information to determine shift scheduling and electronic pressure control.

FUNCTION
If a malfunction occurs in the AP sensor circuit, the PCM will recognize that the AP signal is out of specification. The PCM will then operate the E4OD at a high line pressure to prevent transmission damage. This higher line pressure results in harsh upshifts and engagements.
