TP Sensor Learn

NOTE: Ensure accelerator and brake pedals are free from any obstructions while performing 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 due to the fact that 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, leaving engine off. Wait 30 seconds, then turn ignition switch to LOCK position. Wait an additional 30 seconds.
