Crankshaft Position and Engine Speed Sensor

Crankshaft Position And Engine Speed Sensor

Description
The crankshaft sensor is checked for loss of signal during cranking and engine running conditions. When the appropriate entry conditions have been met a loss of sensor pulses for greater than the predefined time will register a fault. If the fault is registered on 2 drive cycles then the MIL will illuminate.

Additionally if the number of crankshaft 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 synchronizing then a crankshaft range performance fault is registered. If the fault is registered on 2 drive cycles then the MIL will illuminate.





If the above table does not include details of the following enabling conditions: - IAT, ECT, vehicle speed range, and time after engine start-up then the state of these parameters has no influence upon the execution of the monitor.
