P1132

P1132

O2S. Switch point - rich. Sensor 1







Fault symptoms
- CHECK ENGINE.

On-Board Diagnostics

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 0.6 V 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:
- None.

OK report:
- Number of adapted combustions has dropped at some time during the driving cycle.

Fault handling: (See Fault handling III, Other emission-related components and functions for more information.) Fault Handling III, Other Emission-Related Component & Function
- Type III.
