Throttle Position Sensor: Testing and Inspection

THROTTLE POSITION SENSOR LEARN PROCEDURE
If the Throttle Position (TP) sensor or throttle body is replaced, the Electronic Brake Transmission Control Module (EBTCM) must "learn" the TP sensor idle position voltage with the new component(s) installed. This is necessary to ensure effective engine torque reduction during ASR events. The procedure requires a T-1 (Tech 1) Scanner or T-1OO (CAMS) unit, and will be described using a Tech 1.
