PINPOINT TEST DV: Throttle Body Assembly Electronic Throttle Control (ETC): Introduction

WARNING: This page does not describe the selected car, but rather 31 other vehicles, including the 2008 Mercury Sable, 2008 Mercury Mountaineer, 2008 Mercury Milan, 2008 Mercury Mariner, and 2008 Mercury Grand Marquis. However, it is still accessible from the selected car via links, so may be relevant.

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, TP1, TP2, TACM+, and TACM-
powertrain control module (PCM) (12A650)
