Secondary Throttle Position Sensor Malfunction
OPERATIONIf the secondary throttle position sensor circuit, located between the ECCS Control Module (ECM) and the Transmission Control Module (TCM), malfunctions, the ECM will receive a Traction Control System (TCS) output (ON-OFF) signal. This in turn activates the TCS to control engine operation. In other words, while the TCS is operating with the engine in a fail-safe mode, vehicle acceleration will decrease only slightly.
CANCELLATION
Activation of the fail-safe system is canceled each time the ignition switch is turned OFF. The system is reactivated if all of the activating conditions are satisfied after turning the ignition switch from OFF to ON.
