DESCRIPTION
In the VVT (Variable Valve Timing) system, the appropriate intake and exhaust valve open and close timing is controlled by the ECM. The ECM performs intake and exhaust valve control by performing the following: 1) controlling the camshaft and camshaft timing oil control valve, and operating the camshaft timing gear; and 2) changing the relative positions of the camshaft and crankshaft.
| DTC No. | DTC Detection Condition | Trouble Area |
| P0016 | Deviation in the crankshaft position sensor signal and VVT sensor (for Intake Side Bank 1) signal (2 trip detection logic). | Valve timing Camshaft timing oil control valve assembly (bank 1) Camshaft timing gear assembly ECM |
| P0017 | Deviation in the crankshaft position sensor signal and VVT sensor (for Exhaust Side Bank 1) signal (2 trip detection logic). | Valve timing Camshaft timing oil control valve assembly (bank 1) Camshaft timing exhaust gear assembly ECM |
| P0018 | Deviation in the crankshaft position sensor signal and VVT sensor (for Intake Side Bank 2) signal (2 trip detection logic). | Valve timing Camshaft timing oil control valve assembly (bank 2) Camshaft timing gear assembly ECM |
| P0019 | Deviation in the crankshaft position sensor signal and VVT sensor (for Exhaust Side Bank 2) signal (2 trip detection logic). | Valve timing Camshaft timing oil control valve assembly (bank 2) Camshaft timing exhaust gear assembly ECM |
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 illuminates the MIL and stores DTC P0016 (Bank 1) or P0018 (Bank 2).
To monitor the correlation of the exhaust 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 exhaust valve timing is set to the most advanced angle while the engine is idling. If the VVT learned value is out of the specified range in consecutive driving cycles, the ECM illuminates the MIL and stores DTC P0017 (Bank 1) or P0019 (Bank 2).

INSPECTION PROCEDURE
- HINT:
*: The No. 1 cylinder is the cylinder which is farthest from the transmission.
| 1.CHECK FOR ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0016, P0017, P0018 OR P0019) |
Connect the GTS to the DLC3.
Turn the engine switch on (IG).
Turn the GTS on.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
Read DTCs.
| Result | Proceed to |
| P0016, P0017, P0018 or P0019 is output | A |
| P0016, P0017, P0018 or P0019 and other DTCs are output | B |
- HINT:
- If any DTCs other than P0016, P0017, P0018 or P0019 are output, perform troubleshooting for those DTCs first.
|

| A | |
| 2.PERFORM ACTIVE TEST USING GTS (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 GTS to the DLC3.
Start the engine.
Turn the A/C on.
Turn the GTS 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) or Control the VVT Exhaust Linear (Bank 1) or Control the Exhaust VVT Linear (Bank 2) / All Data / VVT Change Angle #1, VVT Change Angle #2, VVT Ex Chg Angle #1, VVT Ex Chg Angle #2.
Perform the Active Test. Check that the displacement angle varies.
- OK:
- Displacement angle varies.
