  2. Select F5 (TP SENSR LEARN). Press up arrow to begin learn procedure. Wait for Tech-1 scan tester to indicate COMPLETE. Turn ignition off. Disconnect Tech-1 scan tester.
NOTE: Ensure accelerator and brake pedals are free from any obstructions while performing TP sensor/idle learn procedure. PCM will not perform learn function with accelerator pedal or brake pedal obstructions.
