P2100



The ECM detects the output circuit for the TAC motor is open, shorted to ground, or shorted to a voltage. The condition exists fro greater than 1 s.



P2101



The ECM detects a 4-50 percent difference between the commanded and the actual throttle plate position, dependant upon the rate of commanded



throttle movement. The condition exists for 1 s.



P2102



The ECM detects an overheat condition with the output driver. The condition exists for 1 s.



P2103



The ECM detects an over load condition with the output driver. The condition exists for 1 s.



P2119



The ECM determines that the throttle valve did not return to the rest position within 1 s. The condition exists for greater than 1 s, or a cumulative of



10 s.



Action Taken When the DTC Sets



DTCs P0638, P2100, P2101, P2102, P2103, and P2119 are Type A DTCs.



Conditions for Clearing the DTC



DTCs P0638, P2100, P2101, P2102, P2103, and P2119 are Type A DTCs.



Diagnostic Aids



Inspect for a condition in which the throttle valve may have been held open. For example, ice may have formed in the throttle bore causing the



throttle valve not to close.
