Faulty Signal. Permanent Fault

Faulty signal. Permanent fault

Checking the oil pressure
- Check the engine oil quality. Check for contaminants particularly
- Replace the engine oil if necessary
- Check that the engine oil pressure is not low. See Oil pressure: Inspecting and replacing the oil pressure sensor Inspecting And Replacing The 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 variable valve timing (VVT) control valve Replacing The Variable Valve Timing (VVT) Control Valve.

Activating the continuous variable valve timing (VVT) test

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




- 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 104°C throughout the entire test.

- Click the VCT2000 symbol to activate the CVVT test
- Wait until the engine coolant temperature (ECT) exceeds 50°C
- Start the continuous variable valve timing (VVT) test. The control module checks the reaction time of the CVVT system to the signal transmitted by the control module by checking the change in the camshaft
- Wait until the continuous variable valve timing (VVT) test is complete. CVVT test complete YES is displayed when the test is complete. There is a fault if CVVT test YES is not displayed within approximately 30 seconds
- Check the result of the CVVT test. The CVVT test results are read off automatically when the test has been correctly completed
- Check that the CVVT test was completed within 30 seconds and that the reaction time is 1.5 seconds or lower. There is a fault if the reaction time exceeds 1.5 seconds.





The CVVT test was completed within 30 seconds and the reaction time is 1.5 seconds or lower.

Information

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

No - Attempt New Test
