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 multimeter, ISAT scan tool or test lamp while doing this.

Diagnostic procedure

1. Check the control module's electrical interface




- Unplug the camshaft position sensor's connector.

- Turn the ignition switch to the ON position.

- Take voltage readings between:


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:


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:

- Evaluation of driving cycle:


Has the diagnostic trouble code recurred?

yes

Continue as described in .


no

The steps taken to rectify the fault were correct.
