SFI SYSTEM, Diagnostic DTC:P0010, P0020
| DTC Code | DTC Name |
|---|---|
| P0010 | Camshaft Position "A" Actuator Circuit (Bank 1) |
| 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.
| DTC Code | DTC Detection Condition | Trouble Area |
|---|---|---|
| P0010 | An open or short in the Camshaft Oil Control Valve (OCV) for intake side (for Bank 1) circuit (1 trip detection logic). |
|
| P0020 | An open or short in the OCV for intake side (for Bank 2) circuit (1 trip detection logic). |

Tech Tips
This DTC relates to the Camshaft Oil Control Valve (OCV).
MONITOR 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.

Tech Tips
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.
PROCEDURE
-
CHECK DTC
-
Clear DTC after recording the freeze frame data and DTC Click here.
-
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.
OK
