4.11.1 Description
The crankshaft position sensor is checked for loss of signal during engine cranking and engine running conditions. When the appropriate entry conditions have been met, a loss of sensor pulses for greater than a predefined time will register a fault. If the fault is registered on 2 drive cycles the MIL will illuminate.
Additionally, if the number of crankshaft position sensor pulses is incorrect by more than one pulse in any one engine revolution then a fault event is recorded. If the number of fault events exceeds the limit without the engine synchronising, a crankshaft position sensor range/performance fault is registered. If the fault is registered on 2 drive cycles the MIL will illuminate.
