Accelerator Pedal Position (APP) Sensor

WARNING: This page is about a different car, the 2011 Ford F550 Super Duty and 2011 Ford F450 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

The APP  sensor is part of the accelerator pedal assembly. The APP  detects the position of the accelerator pedal and inputs this information as a voltage signal to the PCM. The PCM uses APP  sensor information in determining line pressure, shift scheduling and TCC  operation. Failure of this sensor will cause the transmission to operate at high line pressure to avoid damage to the transmission. This high line pressure causes harsh upshifts and harsh engagements.
