Conditions for Setting the DTC

P0638

* The ECM detects that the commanded duty cycle for the range test high is greater than 80 percent.

OR

* The ECM detects that the commanded duty cycle for the range test low is greater than 80 percent.

* Either condition exists for greater than 1 second, or a cumulative of 10 s.

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.

P2119

The ECM determines that the throttle valve did not return to the rest position within 1 second. The condition exists for greater than 1 s.

Action Taken When the DTC Sets

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

Conditions for Clearing the DTC

DTCs P0638, P2100, P2101, 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.
