TOYOTA 2AR-FE ENGINE CONTROL SFI SYSTEM P0010 Camshaft Position “A” Actuator Circuit (Bank 1)
DESCRIPTION:
The Variable Valve Timing (VVT) system adjusts the intake valve timing to improve driveability. The engine oil pressure turns the VVT controller to adjust the valve timing.
The camshaft timing oil control valve assembly 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 No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Memory |
|---|---|---|---|---|---|
| P0010 | Camshaft Position “A” Actuator Circuit (Bank 1) | Open or short in camshaft timing oil control valve assembly (for intake camshaft) circuit (1 trip detection logic). | ·Open or short in camshaft timing oil control valve assembly (for intake camshaft) circuit·Camshaft timing oil control valve assembly (for intake camshaft)·ECM | Comes on | DTC stored |
MONITOR DESCRIPTION:
This DTC is designed to detect an open or short in the camshaft timing oil control valve assembly (for intake camshaft) circuit. If the camshaft timing oil control valve assembly duty-cycle is excessively high or low while the ignition switch to ON or the engine is running, the ECM will illuminate the MIL and store this DTC.
CONFIRMATION DRIVING PATTERN:
- Connect the GTS to the DLC3.
2. Turn the ignition switch to ON.
3.Turn the GTS on.
4.Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
5.Turn the ignition switch off and wait for at least 30 seconds.
6.Turn the ignition switch to ON.
7.Turn the GTS on.
8.Wait 5 seconds or more.
9.Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
10.Read the pending DTCs.HINT:
· If a pending DTC is output, the system is malfunctioning.
· If a pending DTC is not output, perform the following procedure.
11. Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
12. Input the DTC: P0010.
13. Check the DTC judgment result.
| GTS Display | Description |
|---|---|
| NORMAL | ·DTC judgment completed·System normal |
| ABNORMAL | ·DTC judgment completed·System abnormal |
| INCOMPLETE | ·DTC judgment not completed·Perform driving pattern after confirming DTC enabling conditions |
| N/A | ·Unable to perform DTC judgment·Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit |
HINT:
· If the judgment result shows NORMAL, the system is normal.
· If the judgment result shows ABNORMAL, the system has a malfunction.
· If the judgment result shows INCOMPLETE or N/A, perform the Confirmation Driving Pattern and check the DTC judgment result again.
