DTC P0016 Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A) |
DESCRIPTION
The ECM optimizes the valve timing by using the Variable Valve Timing (VVT) system to control the intake camshaft. The VVT system includes the ECM, the camshaft timing oil control valve assembly and the VVT controller (camshaft timing gear assembly). The ECM sends a target duty-cycle control signal to the camshaft timing oil control valve assembly. This control signal regulates the oil pressure supplied to the VVT controller. The VVT controller can advance or retard the intake camshaft.| DTC No. | Detection Condition | Trouble Area |
| P0016 | Deviation between crankshaft and camshaft position sensor signals (2 trip detection logic) |

Refer to DTC P0010 (Link)INSPECTION PROCEDURE
- 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 P0016) |
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 P0016 is output A DTC P0016 and other DTCs are output B
- HINT:
- If any DTCs other than P0016 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 and turn the tester on.
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 P0016) |
Connect the intelligent tester to the DLC 3.
Turn the ignition switch to ON.
Turn the tester on.
Clear the DTCs (CAMRY_ACV40 RM000000PDK0LEX.html).
Start the engine and warm it up.
Idle the engine for 5 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.
Drive the vehicle for 2 to 3 minutes.
- CAUTION:
- When performing the confirmation driving pattern, obey all speed limits and traffic laws.
Idle the engine for 5 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 P0016 is output B
- HINT:
- DTC P0016 may be stored when foreign objects in the 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 with 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
 |
Reinstall the oil control valve filter (CAMRY_ACV40 RM000000YI701HX_01_0006.html).
|
| ||||
| OK | |
| 7.INSPECT CAMSHAFT TIMING GEAR ASSEMBLY |
Inspect the camshaft timing gear assembly (CAMRY_ACV40 RM000001AN6007X_01_0012.html).
|
| ||||
| OK | |
| 8.CHECK WHETHER DTC OUTPUT RECURS (DTC P0016) |
Connect the intelligent tester to the DLC 3.
Turn the ignition switch to ON.
Turn the tester on.
Clear the DTCs (CAMRY_ACV40 RM000000PDK0LEX.html).
Start the engine and warm it up.
Idle the engine for 5 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.
Drive the vehicle for 2 to 3 minutes.
- CAUTION:
- When performing the confirmation driving pattern, obey all speed limits and traffic laws.
Idle the engine for 5 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 P0016 is output B
- HINT:
- DTC P0016 may be stored when foreign objects in the 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.
