Continuous Variable Valve Timing (CVVT) Test

Continuous variable valve timing (CVVT) test

Activating the continuous variable valve timing (VVT) test




- Start the engine. Allow the engine to 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.

Yes - VERIFIED

No - VERIFICATION FAILED
