Diagnostic Aids

WARNING: This page is about a different variant/trim than selected.

Engine acceleration will be compromised and AT downshifts delayed when operating in the Fail-safe mode.
Most TAC system parameters displayed on the scan tool freeze when the MIL illuminates and the TAC DTC sets.
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. Observe the Freeze Frame/Failure Records.
The throttle valve is spring loaded to a slightly open position. The throttle valve should move open and to the closed position without binding under the normal spring tension.
The throttle should NOT be free to move open or closed WITHOUT spring tension.
DTC P2119 can set when there is approximately 10 ohms in the TAC motor control circuits.
