DTC DETECTION CONDITION
TROUBLE AREA
P0010
Open or short in OCV (for intake side of
bank 1) circuit
(1 trip detection logic)
Open or short in OCV (for intake side of
bank 1) circuit
P0020
Open or short in OCV (for intake side of
bank 2) circuit
(1 trip detection logic)
Open or short in OCV (for intake side of
bank 2) circuit
HINT:
This DTC relates to the Camshaft Timing Oil Control Valve (OCV).
MONITOR DESCRIPTION
This DTC is designed to detect opens or shorts in the camshaft timing oil control valve assembly (OCV) circuit.
If the OCV's duty-cycle is excessively high or low while the engine is running, the ECM will illuminate the MIL
and set the DTC.

CONFIRMATION DRIVING PATTERN
Connect the Techstream to the DLC3.
1.
Turn the ignition switch to ON and turn the Techstream on.
2.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC operation).
3.
Turn the ignition switch off and wait for at least 30 seconds.
4.
Turn the ignition switch to ON and turn the Techstream on.
5.
Wait 5 seconds.

Unable to perform DTC judgment
If the test result is INCOMPLETE or N/A and no pending DTC is output, perform a universal trip and
check for permanent DTCs
.
HINT:
If a permanent DTC is output, the system is malfunctioning.
If no permanent DTC is output, the system is normal.

WIRING DIAGRAM
INSPECTION PROCEDURE
HINT:
Read freeze frame data using the Techstream. 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.
PROCEDURE
1.
CHECK DTC
3UR-FBE ENGINE CONTROL SYSTEM: SFI SYSTEM: P0010,P002...
OK
(a) Clear DTC after recording the freeze frame data and DTC
.
(b) Turn the ignition switch off.
(c) Allow the engine to idle and check DTC.
(d) Check that P0010 or P0020 is not output.
OK:
P0010 or P0020 is not output.
NG
GO TO STEP 2
OK
CHECK FOR INTERMITTENT PROBLEMS
2.
INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY (FOR INTAKE
SIDE)
(a) Inspect the camshaft timing oil control valve assembly (for intake side)
.
NG
REPLACE CAMSHAFT TIMING OIL CONTROL
VALVE ASSEMBLY (FOR INTAKE SIDE)
3.
CHECK HARNESS AND CONNECTOR (CAMSHAFT TIMING OIL CONTROL VALVE
ASSEMBLY (FOR INTAKE SIDE) - ECM)
(a) Disconnect the D75 or D76 camshaft timing oil control valve assembly connector.
(b) Disconnect the D74 ECM connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:
