On-Board Diagnostics
Type of diagnosis:
|
-
|
Test 1: Continuous. But interrupted when fault criteria fulfilled and does not restart until next driving cycle.
|
|
-
|
Test 2: Once per driving cycle. Interrupted when fault criteria fulfilled or OK reported. 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 temperatures must exceed -7°C.
|
|
-
|
Test 1: Engine running. Closed loop blocked in rich or lean position for a number of combustions to hold current from oxygen sensor 2 at 0.6 V. The required number of combustions is adapted.
|
|
-
|
Test 2: 3 minutes since start of engine. The vehicle is driven with an engine speed of 1300-2200 rpm with a load corresponding to 250-500 mg/c (air mass/combustion). Closed loop is active and stable. Air mass/combustion stable. Purging is active. Coolant temperature above 60°C. No change in brake light status. When all conditions are fulfilled wait 3 sensor transitions. Then count the number of combustions during 15 sensor transitions.
|
Fault criteria:
|
-
|
Test 1: The adapted number of combustions during which closed loop is blocked in rich or lean position exceeds 50.
|
|
-
|
Test 2: Number of combustions exceeding 460.
|
Dependents:
|
-
|
P0116, P0117, P0118, P0131, P0132 and P0134.
|
System reaction to a fault:
OK report:
|
-
|
Test 1: Number of adapted combustions has dropped at some time during the driving cycle. Test 2 performed once and fault criteria not fulfilled.

Diagnostic help
Fault diagnosis concerns an internal fault in the sensor.
Functions in the diagnostic tool related to the fault:

Note
|
|
Oxygen sensor receives reference oxygen from the surrounding air via the connecting cables. For this reason, electrical contact spray or grease
must not
be used on the oxygen sensor connector.
