TP Sensor Learn

If a NEW TP sensor, throttle body or PCM is installed, PCM must learn new TP sensor offset. This procedure is necessary because of manufacturing tolerances during minimum air adjustment, TP sensor being non-adjustable on throttle body and TP sensor manufacture. 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 another 30 seconds.
