Type of diagnosis:
|
-
|
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 temperature must exceed -7°C.
|
|
-
|
Engine running for 3 min. Car driven at engine speed 1300-2200 rpm with load corresponding to 250-500 mg/c (air mass/combustion). Closed loop active and stable. Air mass/combustion stable. Purging active. Coolant temperature above 70°C. When all the criteria have been fulfilled, the number of ignitions during 2 sensor transitions is counted.
|
