Throttle Position Sensor/Switch: Description and Operation
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.
