On-Vehicle Inspection [12/2019 - 10/2022]: Procedure
- INSPECT CAMSHAFT TIMING OIL CONTROL SOLENOID ASSEMBLY
- Start the engine.
- Inspect the camshaft timing oil control solenoid assembly (for intake side).
- Read the Data List while performing the Active Test with the engine idling.

GTS Operation Data List (Intake VVT Change Angle Bank 1 or Intake VVT Change Angle Bank 2) -100% to 100% Varies by 70 DegFR or more If the result is not as specified, check the camshaft timing oil control solenoid assembly, wire harness and ECM.
- Read the Data List while performing the Active Test with the engine idling.
- Inspect the camshaft timing oil control solenoid assembly (for exhaust side).
- Check the engine speed while operating the camshaft timing oil control solenoid assembly (for exhaust camshaft) using the GTS.

Refer to "Data List / Active Test" [Exhaust VVT OCV Control Duty Ratio Bank 1, Exhaust VVT Change Angle Bank 1, Exhaust VVT OCV Control Duty Ratio Bank 2 and Exhaust VVT Change Angle Bank 2].
Refer to DATA LIST / ACTIVE TEST [12/2019 - 09/2020] , or refer to DATA LIST / ACTIVE TEST [09/2020 - 10/2022]
If the result is not as specified, check the camshaft timing oil control solenoid assembly, wire harness and ECM.
- Check the engine speed while operating the camshaft timing oil control solenoid assembly (for exhaust camshaft) using the GTS.
