Land Cruiser URJ200 URJ202 GRJ200 VDJ200 - 1UR-FE ENGINE CONTROL
INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY
CHECK HARNESS AND CONNECTOR (CAMSHAFT TIMING OIL CONTROL VALVE - ECM)
DTC P0010 Camshaft Position "A" Actuator Circuit (Bank 1)
DTC P0020 Camshaft Position "A" Actuator Circuit (Bank 2)
DESCRIPTION
These DTCs are designed to detect opens or shorts in the camshaft timing oil control valve circuit. If the camshaft timing oil control valve 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 and exhaust valve timing to improve driveability. The engine oil pressure turns the camshaft timing gear to adjust the valve timing. The camshaft timing oil control valve 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 of the solenoid (duty cycle) in accordance with the camshaft position, crankshaft position, throttle position, etc.
| DTC No. | DTC Detection Condition | Trouble Area |
| P0010 | Open or short in the camshaft timing oil control valve for intake side (for Bank 1) circuit (1 trip detection logic). | Open or short in camshaft timing oil control valve for intake side (for Bank 1) circuit Camshaft timing oil control valve assembly for intake side (for Bank 1) ECM |
| P0020 | Open or short in the camshaft timing oil control valve for intake side (for Bank 2) circuit (1 trip detection logic). | Open or short in camshaft timing oil control valve for intake side (for Bank 2) circuit Camshaft timing oil control valve assembly for intake side (for Bank 2) ECM |
- HINT:
- These DTCs relate to the camshaft timing oil control valve.
MONITOR DESCRIPTION
These DTCs are designed to detect opens or shorts in the camshaft timing oil control valve circuit. If the camshaft timing oil control valve duty cycle is excessively high or low while the engine is running, the ECM will illuminate the MIL and store the DTC.
The monitor for this DTC runs 5 seconds after the engine switch is turned on (IG).
CONFIRMATION DRIVING PATTERN
Turn the engine switch on (IG) and wait for 5 seconds or more.
WIRING DIAGRAM
INSPECTION PROCEDURE
- HINT:
Read freeze frame data using the GTS. 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.
*: 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 FOR DTC |
Clear the DTCs after recording the freeze frame data and DTCs ().
Turn the engine switch off.
Start the engine and allow it to idle. Then check for DTCs.
Check that P0010 or P0020 is not output.
- OK:
- P0010 or P0020 is not output.

| 2.INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY |
Inspect the camshaft timing oil control valve assembly ().
|

| OK | |
| 3.CHECK HARNESS AND CONNECTOR (CAMSHAFT TIMING OIL CONTROL VALVE - ECM) |
Disconnect the camshaft timing oil control valve connector.
Disconnect the ECM connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
