ENGINE MANAGEMENT SYSTEM
Voltage generation from the CKP sensor is relative to engine speed. The values from a good CKP sensor are as
follows:
•
•
2 to 3 volts with engine cranking.
Rising to 6 to 6.5 volts from 1000 rev/min upwards.
The above readings are dependent upon the correct air gap between the tip of the CKP sensor and the passing
teeth of the reluctor ring.
The CKP sensor can fail or supply an incorrect signal if one or more of the following occurs:
•
•
•
•
•
•
Sensor assembly loose.
Incorrect spacer fitted.
Sensor open circuit.
Sensor short circuit.
Incorrect fitting and integrity of the sensor.
Water ingress.
In the event of a CKP sensor signal failure, any of the following symptoms may be observed:
•
•
•
Engine cranks but fails to start.
Engine misfires (CKP sensor incorrectly fitted).
Engine runs roughly or stalls (CKP sensor incorrectly fitted).
The CKP sensor does not have a back-up strategy. If it fails the engine will stop running and fail to start.
