Signal Too High

Signal too high

Checking the status




- Start the engine and run it to normal operating temperature.
Read off the camshaft shift angle and the camshaft shift angle, desired value.
Check that the camshaft's gear angle and reference value for the camshaft's gear angle correspond with an accuracy of about 5 degrees CA when idling and when the engine is warm. Rev the engine a few times and check again at idle speed that the values correspond.
The difference between the values can be read off in the lower digital display.
The fault is permanent if the values do not correspond. The fault is intermittent if the values correspond.










Continue - Checking components

-------------------------------------------------

Checking components
Check the engine oil level and quality. Check for contaminants in particular.
Remove the camshaft reset valve. Check the oil ducts for the cylinder head for the camshaft reset valve. Check for blockages and dirt.

Hint: Faults may result from dirt in the camshaft reset valve. Try cleaning the valve.

Try a new camshaft reset valve if the above remedy does not solve the fault.

Hint: The fault may also have been caused by an internal fault in the variable valve timing unit. The variable valve timing unit may be damaged if the above fault-tracing and corrective action do not remedy the fault.

Remedy as necessary.

Hint: After carrying out the repair, check that the fault has been remedied.




- Start the engine and run it to normal operating temperature.
Read off the camshaft shift angle and the camshaft shift angle, desired value.
At idle speed with the engine at operating temperature, check that the camshaft shift angle and the desired value for the camshaft shift angle correspond with an accuracy of approximately 8° CA. Rev the engine a few times and check again at idle speed that the values correspond.
The difference between the values can be read off in the lower digital display.

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.

Do you want to exit fault-tracing?

Yes - Exit Fault-Tracing
