WIRING DIAGRAM
Refer to DTC P0010 (CAMRY_ACV40 RM000000PDW0F5X_07.html).INSPECTION PROCEDURE
- HINT:
- DTC P0011 or P0012 may be stored when foreign objects in the engine oil are caught in some parts of the system. The DTC will remain set even if the system returns to normal after a short time. Those foreign objects may then be captured by the oil filter.
- HINT:
- Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. 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.
| 1.CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0011 OR P0012) |
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Turn the tester on.
Enter the following menus: Powertrain / Engine and ECT / DTC.
Read the DTCs.
- Result:
Result Proceed to DTC P0011 or P0012 is output A DTC P0011 or P0012 and other DTCs are output B
- HINT:
- If any DTCs other than P0011 or P0012 are output, troubleshoot those DTCs first.

| 2.PERFORM ACTIVE TEST USING INTELLIGENT TESTER (OPERATE OIL CONTROL VALVE) |
Connect the intelligent tester to the DLC3.
Start the engine.
Turn the tester on.
Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the VVT Linear (Bank 1).
Check the engine speed while operating the camshaft timing oil control valve assembly using the tester.
- OK:
Tester Operation Specified Condition 0% Normal engine speed 100% Engine idles roughly or stalls
|
| ||||
| OK | |
| 3.CHECK WHETHER DTC OUTPUT RECURS (DTC P0011 OR P0012) |
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Turn the tester on.
Clear the DTCs (CAMRY_ACV40 RM000000PDK0LEX.html).
Start the engine and warm it up.
Drive the vehicle at approximately 60 km/h (37 mph) for 10 minutes or more.
- CAUTION:
- When performing the confirmation driving pattern, obey all speed limits and traffic laws.
Idle the engine for 3 minutes or more.
Enter the following menus: Powertrain / Engine and ECT / DTC.
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.
Repeat the pattern of accelerating the vehicle from rest to approximately 60 km/h (37 mph) and then decelerating the vehicle 10 to 15 times.
- CAUTION:
- When performing the confirmation driving pattern, obey all speed limits and traffic laws.
- HINT:
- Depress the accelerator pedal by a large amount.
Idle the engine for 3 minutes or more.
Enter the following menus: Powertrain / Engine and ECT / DTC.
Read the pending DTCs.
- Result:
Result Proceed to DTC is not output A DTC P0011 or P0012 is output B
- HINT:
- DTC P0011 or P0012 may be stored when foreign objects in engine oil are caught in some parts of the system. The DTC will remain stored even if the system returns to normal after a short time. These foreign objects may then be captured by the oil filter.

| 4.INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY |
Remove the camshaft timing oil control valve assembly.
 |
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
Text in Illustration *1 Component without harness connected
(Camshaft Timing Oil Control Valve Assembly)
Connect the positive (+) battery terminal to terminal 1 and connect the negative (-) battery terminal to terminal 2. Check the valve operation.
- OK:
- Valve moves quickly.
 |
Reinstall the camshaft timing oil control valve assembly.
|
| ||||
| OK | |
| 5.CHECK VALVE TIMING |
Remove the cylinder head cover.
 |
Turn the crankshaft pulley, then align its groove with the timing mark "0" on the timing chain cover.
Check that the point marks on the camshaft timing gears are aligned with the timing chain cover surface as shown in the illustration.
If not, turn the crankshaft 1 revolution (360°), then align the marks as above.- OK:
- Alignment marks on camshaft timing gears are aligned as shown in the illustration.
Text in Illustration *1 Alignment Marks *2 Groove
Reinstall the cylinder head cover.
|
| ||||
| OK | |
| 6.INSPECT OIL CONTROL VALVE FILTER |
Remove the oil control valve filter (CAMRY_ACV40 RM000000YI601HX_01_0035.html).
Check that the oil control valve filter is not clogged.
- OK:
- Filter is not clogged.
Text in Illustration *1 Oil Control Valve Filter
