Pinpoint Test DV: Throttle Body Assembly Electronic Throttle Control (ETC): Introduction

WARNING: SUBSTANTIAL OPENING AND CLOSING TORQUE IS APPLIED BY THIS SYSTEM. TO PREVENT INJURY, BE CAREFUL TO KEEP FINGERS AWAY FROM THROTTLE MECHANISM WHEN ACTUATED. FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN PERSONAL INJURY.

NOTE: The voltage of the TP2 circuit and PID reaches a limit of approximately 4.5 volts at approximately 45 degrees of throttle angle.

This pinpoint test is intended to diagnose the following:

electronic throttle body (ETB) (9F991)
electronic throttle body throttle position sensor (ETBTPS) (9E928)
harness circuits: ETCRTN, ETCREF, TPS1-NS, TPS2-PS, TACM+, and TACM-
powertrain control module (PCM) (12A650)
