Inspection Procedure
HINT:
Read freeze frame data using a Techstream. Freeze frame data record 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 FOR DTC
- Clear the DTCs after recording the freeze frame data and DTCs.
- Allow the engine to idle and check for DTCs.
- Check whether P0010 or P0020 is present.
OK: P0010 or P0020 is present.
NG: CHECK FOR INTERMITTENT PROBLEMS
OK: Go to Next Step
- INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY
- Disconnect the OCV connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
TESTER CONNECTIONS SPECIFIED CONDITIONS CHARTTester Connections Specified Conditions 1 - 2 6.9 to 7.9 Ω at 20°C (68°F) - Reconnect the OCV connector.
NG: REPLACE CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY (See REMOVAL )
OK: Go to Next Step
- CHECK HARNESS AND CONNECTOR (OCV ECM)
- Disconnect the B3 ECM connector.
- Disconnect the B12 or B26 OCV connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance for Bank 1
TESTER CONNECTIONS SPECIFIED CONDITIONS CHARTTester Connections Specified Conditions B12-1 - OC1 + (B3-17) Below 1 Ω B12-1 - Body ground 10 kΩ or higher B12-2 - OC1 - (B3-16) Below 1 Ω B12-2 - Body ground 10 kΩ or higher Standard Resistance for Bank 2
TESTER CONNECTIONS SPECIFIED CONDITIONS CHARTTester Connections Specified Conditions B26-1 - OC2 + (B3-15) Below 1 Ω B26-1 - Body ground 10 kΩ or higher B26-2 - OC2 - (B3-14) Below 1 Ω B26-2 - Body ground 10 kΩ or higher - Reconnect the ECM connector.
- Reconnect the OCV connector.
NG: REPAIR OR REPLACE HARNESS OR CONNECTOR
OK: REPLACE ECM (See REMOVAL )
