Inspection Procedure
WARNING: This page is about a different car, the 2008 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.
HINT:
Read freeze frame data using Techstream. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.
- CHECK DTC
- Clear DTC after recording the freeze frame data and DTC.
- Turn the ignition switch OFF.
- Allow the engine to idle and check DTC.
- Check that P0010 or P0020 is present.
OK:
P0010 or P0020 is present.
OK: CHECK FOR INTERMITTENT PROBLEMS
NG: Go to next step
- INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY
- Disconnect the B44 or B60 OCV connector.
- Measure the resistance between the terminals of the OCV.
Standard resistance:
6.9 to 7.9 Ω at 20°C (68°F)
- Reconnect the OCV connector.
NG: REPLACE CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY
OK: Go to next step
- CHECK WIRE HARNESS (OCV - ECM)
- Disconnect the B44 or B60 OCV connector.
- Disconnect the B30 ECM connector.
- Measure the resistance of the wire harness side connectors.
