Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition

Note! This diagnostic trouble code (DTC) status is an event controlled diagnostic trouble code (DTC). An event controlled diagnostic trouble code (DTC) does not mean that there is a fault in the control module when it is active, but is designed as information.

Engine control module (ECM) monitors the engine's heated oxygen sensor control. A DTC is stored if the control module detects that the heated oxygen sensor (HO2S) during fuel shut-off reacts slower than expected.
The diagnostic trouble code (DTC) can be diagnosed when the engine is running.

Substitute value
- Nothing.

Possible source
- This diagnostic trouble code (DTC) is not caused by a fault that needs to be remedied.

Fault symptom[s]
- Warning lights and chimes/Malfunction Indicator Light ("Check engine" light) indication/no indication
