DTC P0010 Camshaft Position "A" Actuator Circuit (Bank 1)

DTC P0020 Camshaft Position "A" Actuator Circuit (Bank 2)

DESCRIPTION

This DTC is designed to detect opens or shorts in the camshaft oil control valve (OCV) circuit. If the OCV duty-cycle is excessively high or low while the engine is running, the ECM will illuminate the MIL and store the DTC.

The VVT (variable valve timing) system adjusts the intake valve timing to improve the driveability. The engine oil pressure turns the camshaft actuator to adjust the valve timing. The OCV is a solenoid valve and switches the engine oil line. The valve moves when the ECM applies 12 V to the solenoid. The ECM changes the energizing time to the solenoid (duty-cycle) in accordance with the camshaft position, crankshaft position, throttle position, etc.

INSPECTION PROCEDURE

HINT:

Read freeze frame data using the intelligent tester. 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.

Bank 1 refers to the bank that includes the No. 1 cylinder*.
*: The No. 1 cylinder is the cylinder which is farthest from the transmission.

Bank 2 refers to the bank that does not include the No. 1 cylinder.

1.CHECK DTC

Clear DTC after recording the freeze frame data and DTC ().

Turn the engine switch off.

Allow the engine to idle and check DTC.

Check that P0010 or P0020 is not output.

OK:
P0010 or P0020 is not output.

Go to step 2

CHECK FOR INTERMITTENT PROBLEMS ()

2.INSPECT CAMSHAFT OIL CONTROL VALVE ASSEMBLY

Disconnect the C102 or C103 camshaft oil control valve (OCV) connector.

Measure the resistance according to the value(s) in the table below.

Standard Resistance:
Tester Connection Condition Specified Condition
1 - 2 20°C (68°F) 6.9 to 7.9 Ω

REPLACE CAMSHAFT OIL CONTROL VALVE ASSEMBLY ()

OK

3.CHECK HARNESS AND CONNECTOR (OCV - ECM)

Disconnect the C102 or C103 OCV connector.

Disconnect the C45 ECM connector.

Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
C102-1 - C45-58 (OC1+)	Always	Below 1 Ω
C103-1 - C45-52 (OC2+)	Always	Below 1 Ω
C102-2 - C45-57 (OC1-)	Always	Below 1 Ω
C103-2 - C45-51 (OC2-)	Always	Below 1 Ω
C102-1 or C45-58 (OC1+) - Body ground	Always	10 kΩ or higher
C103-1 or C45-52 (OC2+) - Body ground	Always	10 kΩ or higher
C102-2 or C45-57 (OC1-) - Body ground	Always	10 kΩ or higher
C103-2 or C45-51 (OC2-) - Body ground	Always	10 kΩ or higher

REPAIR OR REPLACE HARNESS OR CONNECTOR

REPLACE ECM ()
