Faulty signal. Permanent fault

Checking the oil pressure
- Check the engine oil quality. Check for contaminants particularly
- Replace the engine oil if necessary
- Check whether the engine oil pressure is unstable. See Oil pressure: Inspecting and replacing the oil pressure sensor Inspecting And Replacing Oil Pressure Sensor
- Remedy as necessary.

Was the engine oil pressure incorrect?

Yes - Verification

No - Checking oil ducts

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

Checking oil ducts
- Remove the camshaft reset valve
- Check the oil ducts for the camshaft reset valve and camshaft pulley in the cylinder head for blockages.

Note! If it is suspected that there are any contaminants in the camshaft reset valve it should be replaced.

- Remedy as necessary
- Try a new camshaft reset valve, if no fault is found in the oil ducts.

Other information:
- To remove or replace the camshaft reset valve, see Replacing the camshaft seals Camshaft Seals, Replacing.





Select Continue when the fault has been remedied.

Activating the continuous variable valve timing (VVT) test




- Start the engine and let it idle.

Note! The engine must be idling and the engine coolant temperature (ECT) must be between 50°C and 92°C throughout the entire test.

- Activate the continuous variable valve timing (VVT) test by clicking on the VCT-2000 symbol
- Wait until the engine coolant temperature (ECT) exceeds 50°C
- Start the continuous variable valve timing (VVT) test
- Wait until the continuous variable valve timing (VVT) test is complete. CVVT test complete YES is displayed with the test is complete
- Read off the results of the continuos variable valve timing (VVT) test. The continuous variable valve timing (VVT) test results are read off automatically when the test has been correctly completed
- The OK status will be displayed if the control module does not detect any faults. The NOT OK status will be displayed if the control module detects any faults
- Click the stop button to re-run the test.





Is the OK status displayed?

Yes - VERIFIED

No - VERIFICATION FAILED
