Accelerator Pedal (AP) Sensor - 7.3L Diesel Only

WARNING: This page is about a different car, the 2002 Ford RV Cutaway, 2002 Ford Econoline, 2002 Ford E550 Super Duty, 2002 Ford E450 Super Duty, and 2002 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.

The accelerator pedal (AP) sensor is mounted on the accelerator pedal on vehicles equipped with 7.3 - diesel engines. The AP sensor detects the position of the accelerator pedal and sends this information as a voltage signal to the powertrain control module (PCM). If the AP sensor or related circuits fail to operate in a normal manner, the powertrain control module will recognize that the AP sensor signal is out of specification. The PCM will then operate the transmission at a higher line pressure to prevent transmission damage. This high line pressure causes harsh upshift and engagements.
