DTC P1682for the 2.8L, 3.0L, 3.2L, or 3.6L engine
Circuit / System Description
There are 2?ignition voltage circuits supplied to the engine control module (ECM). The first ignition circuit is provided by the engine controls ignition relay or powertrain relay, through a fuse. This ignition voltage circuit supplies power to all the internal ECM circuits associated with the throttle actuator control (TAC) operation. The second ignition voltage circuit is supplied by the ignition main relay through a fuse, and is used to power the remaining internal ECM circuits. If the ECM detects a voltage difference between the 2?ignition voltage circuits, DTC?P1682 will set.
