4.10.1 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 longer than a predefined time will register a fault. If the fault is registered on two 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 two drive cycles the MIL will illuminate.
