DIAGNOSTIC TROUBLE CODE (DTC) INFORMATION




Condition
When fuel is shut-off, for example during engine braking, the control signal to the AACV is changed. Diagnostic trouble code (DTC) ECM-6207 is stored in the engine control module (ECM) if the ECM registers that the changed control signal has not resulted in a change to the volume of intake air (because the valve is stuck).

Condition
None.

Possible source

Flow too low:
- sticking AACV
- blocked AACV or hose
- defective AACV.

Condition
- low idling speed
- oscillating idling.
