WARNING: SUBSTANTIAL OPENING AND CLOSING TORQUE IS APPLIED BY THIS SYSTEM. TO PREVENT INJURY,
BE CAREFUL TO KEEP FINGERS AWAY FROM WHEN ACTUATED. FAILURE TO FOLLOW
THESE INSTRUCTIONS MAY RESULT IN PERSONAL INJURY.
THROTTLE MECHANISM
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)
-harness circuits: ETCRTN, ETCREF, TP1, TP2, TACM+, and TACM-powertrain control module (PCM) (12A650)
