CAMSHAFT POSITION SENSOR





Fault Symptoms
CHECK ENGINE lamp (MIL) on.
Performance down, continual retardation of the ignition timing.

Conditions.
P0341
^ Engine running.
^ 10 engine revolutions without any information from the camshaft position sensor.

Diagnostic Help.
The cause of the fault could be:
^ A faulty sensor in the distributor.

Check The Wiring.
Intermittent faults may occur as a result of temporary short circuits and breaks in the wiring. Jiggle the wiring at several points and in different directions to ascertain whether the wiring harness, including any connectors, is causing the trouble. Observe the multi meter, ISAT scan tool or test lamp while doing this.





Diagnostic Procedure.
1 Check the control module's electrical interface

- Unplug the camshaft position sensors connector.
- Turn the ignition switch to the ON position.
- Take voltage readings between:
^ pin 1 and battery negative (B-): 5 V
^ pin 2 and battery negative (B-): 5 V
^ Battery positive (B+) and pin 3: 12 V.

Are all readings OK?

YES:
^ Continue with point 3.

NO:
^ Continue with point 2.





2 Check The Wiring between control module and connector

- Check for continuity between the control module and connector as follows:
^ connector pin 1-control module pin 59.
^ connector pin 2-control module pin 44.
^ connector pin 3-control module pin 28.

Is the wiring OK?

YES:
^ Continue with point 4.

NO:
^ Rectify the fault. Continue with point 4.

3.Check the dIstributor

- Check that the field rotor flange is firmly mounted in place and that it rotates with the rotor when the starter motor is run.

Is the distributor OK?

YES:
^ Change the sensor. Continue with point 4.

NO:
^ Rectify the fault in the distributor. Continue with point 4.





4 Final check

- Clear the diagnostic trouble code.
- Implementation of driving cycle:
^ Drive the car at varying loads and engine rpm for 5 minutes.
- Evaluation of driving cycle:
^ Check whether the diagnostic trouble code has recurred.

Has the diagnostic trouble code recurred?

YES:
^ Continue at "Before Replacing a Control Module". Component Tests and General Diagnostics

NO:
^ The steps taken to rectify the fault were correct.
