Type of diagnosis:
|
-
|
Continuous. Terminated when fault criteria fulfilled. Restarts next driving cycle.
|
Enable criteria:
|
-
|
General conditions for this trouble code: Atmospheric pressure must exceed 72 kPa and the engine coolant and intake air temperature must exceed -7°C.
|
|
-
|
Engine running. Closed loop blocked in rich or lean mode for a number of combustions in order to maintain a voltage of 0.6V from oxygen sensor 2. The number of combustions that is required is adapted.
|
Fault criteria:
|
-
|
Closed loop blocked in lean mode for more than 35 combustions.
|
Dependents:
|
-
|
P0115, P0116, P0117, P0118, P0119, P0131, P0132 and P0134.

System reaction to a fault:
OK report:
|
-
|
