DTC P0016 Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A) |
DTC P0018 Crankshaft Position - Camshaft Position Correlation (Bank 2 Sensor A) |
DESCRIPTION
In the VVT (Variable Valve Timing) system, the appropriate intake valve open and close timing is controlled by the ECM. The ECM performs intake valve control by performing the following: 1) controlling the intake camshaft and camshaft timing oil control valve assembly (for intake camshaft), and operating the camshaft timing gear assembly; and 2) changing the relative positions of the camshaft and crankshaft.DTC Code
| DTC Detection Condition
| Trouble Area
|
P0016
| Deviations in the crankshaft and VVT sensor (for bank 1) signals (2 trip detection logic).
| - Mechanical system (Timing chain has jumped tooth or chain stretched)
- Camshaft timing oil control valve assembly
- Oil control valve filter
- Camshaft timing gear assembly
- ECM
|
P0018
| Deviations in the crankshaft and VVT sensor (for bank 2) signals (2 trip detection logic).
|
MONITOR DESCRIPTION
To monitor the correlation of the intake camshaft position and crankshaft position, the ECM checks the VVT learned value while the engine is idling. The VVT learned value is calibrated based on the camshaft position and crankshaft position. The intake valve timing is set to the most retarded angle while the engine is idling. If the VVT learned value is out of the specified range in consecutive driving cycles, the ECM stores DTC P0016 (bank 1) or P0018 (bank 2).
CONFIRMATION DRIVING PATTERN

- Connect the intelligent tester to the DLC3.
- Turn the ignition switch to ON and turn the tester on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC operation).
- Turn the ignition switch off and wait for at least 30 seconds.
- Turn the ignition switch to ON and turn the tester on [A].
- Start the engine and warm it up until the engine coolant temperature reaches 75°C (167°F) or higher [B].
- Idle the engine for 5 minutes or more [C].
- Enter the following menus: Powertrain / Engine and ECT / DTC [D].
- 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.
- Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
- Input the DTC: P0016 or P0018.
- Check the DTC judgment result.
Tester 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 steps [E] through [G].
- Drive the vehicle for 2 to 3 minutes [E].
- CAUTION:
- When performing the confirmation driving pattern, obey all speed limits and traffic laws.
- Idle the engine for 5 minutes or more [F].
- Enter the following menus: Powertrain / Engine and ECT / DTC [G].
- 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.
- Check the DTC judgment result.
- HINT:
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.
WIRING DIAGRAM
Refer to DTC P0335 (HILUX_TGN26 RM000000TCW0QWX_07.html).Refer to DTC P0340 (HILUX_TGN26 RM000000WBZ0J5X_07.html).
INSPECTION PROCEDURE
- HINT:
- Read freeze frame data using the intelligent tester. 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 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 No. 1 cylinder.
1.CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0016 OR P0018) |
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON and turn the tester on.
Enter the following menus: Powertrain / Engine and ECT / DTC.
Read the DTCs.

2.PERFORM ACTIVE TEST USING INTELLIGENT TESTER (OPERATE CAMSHAFT TIMING OIL CONTROL VALVE) |
- HINT:
- If the VVT system can be operated through the Active Test, it can be assumed that the VVT system is operating normally.
Connect the intelligent tester to the DLC3.
Start the engine and turn the tester on.
Warm up the engine.
Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the VVT Linear (Bank 1) or Control the VVT Linear (Bank 2) / All Data / VVT Change Angle #1, VVT Change Angle #2.
Perform the Active Test. Check that the displacement angle varies.
- OK:
- Displacement angle varies.
Adjust the valve timing (HILUX_TGN26 RM0000015D100CX.html).
4.INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY |
Inspect the camshaft timing oil control valve assembly (HILUX_TGN26 RM000000Q7403JX.html).
5.INSPECT OIL CONTROL VALVE FILTER |
Remove the oil control valve filter (HILUX_TGN26 RM0000015D100CX.html).
