Throttle Position Sensor Learn (4.6L)

NOTE: Ensure accelerator and brake pedals are free from any obstructions while performing Throttle Position (TP) sensor learn procedure. PCM will not perform learn function with accelerator pedal or brake pedal obstructions.
  1. If a new TP sensor, throttle body or PCM is installed, PCM must learn new TP sensor offset. This procedure is necessary since TP sensor is not adjustable and may be produced by more than one manufacturer, causing varying tolerances during minimum air adjustment.
  2. High idle at closed throttle or a stall condition may occur if PCM maintains an improper TP sensor offset. To perform TP sensor learn, turn ignition on, engine off. Wait one minute, and then turn ignition off. Wait an additional 15 seconds.
