There are 2 ignition 1 voltage circuits supplied to the Engine Control Module (ECM). The first ignition circuit is provided by the powertrain relay, through a fuse. This ignition 1 voltage circuit supplies power to all the internal ECM circuits associated with the throttle actuator control (TAC) operation. The second ignition 1 voltage circuit is supplied by the run/crank 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 1 voltage circuits

My 2007 GMC envoy Denali after it has been running for a few minutes the engine dies either sitting there or while driving, the engine will turn over but will not fire. P1682 code is confirmed


There are 2 ignition 1 voltage circuits supplied to the engine control module (ECM). The first ignition circuit is
provided by the powertrain relay, through a fuse. This ignition 1 voltage circuit supplies power to all the
internal ECM circuits associated with the throttle actuator control (TAC) operation. The second ignition 1
voltage circuit is supplied by the ignition switch through a fuse, and is used to power the remaining internal
ECM circuits. If the ECM detects a voltage difference between the 2 ignition 1 voltage circuits, DTC P1682
will set.
