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.

Circuit/System Verification



1. Ignition ON, observe the DTC information with a scan tool. Verify DTC P0121, P0122, P0123, P0221, P0222, or P0223 is not set.



瀚慖f a DTC is set refer to DTC P0121-P0123 or P0221-P0223 (Without LF1, LFW) ( See: P Code Charts/P0121) for further diagnosis.



2. Observe the scan tool Throttle Position Sensor voltage parameters. Verify that Throttle Position Sensor 1 voltage is between 3.24-3.54 V, and



Throttle Position Sensor 2 voltage is between 1.36-1.86 V.
