- INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSY (FOR VVTL)
- Start the engine.
- Check the engine speed twice in each of conditions (1) and (2), as described below:
- Disconnect the C2 camshaft timing OCV (Oil Control Valve) connector.
- Apply the positive battery voltage between the terminals of the camshaft timing OCV.
Result:

- B: REPLACE CAMSHAFT TIMING OIL CONTROL VALVE ASSY
- A: GO TO NEXT STEP
- INSPECT ECM (VVL+ - VVL- VOLTAGE)
- Start the engine and warm it up.
- Measure the voltage between terminals VVL+ and VVL- of the ECM connector.
Standard: Between 9 V and 14 V
(Engine speed at 6,500 rpm or more)
