P0016
2GR-FXE ENGINE CONTROL: SFI SYSTEM: P0016,P0018: Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A)
P0018 - Crankshaft Position - Camshaft Position Correlation (Bank 2 Sensor A)
DESCRIPTION
Refer to DTC P0010 P0010.
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).

8. Idle the engine for 5 minutes or more [C].
9. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes / Pending.
10. Read the pending DTC [D].

- If the judgment result shows INCOMPLETE or UNKNOWN, perform steps [E] through [G].
14. Drive the vehicle for 2 to 3 minutes [E].
15. Idle the engine for 5 minutes or more [F].
16. Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.

19. If the test result is INCOMPLETE or UNKNOWN, perform a universal trip and check for permanent DTCs Reading and Clearing Diagnostic Trouble Codes.
HINT
- If a permanent DTC is output, the system is malfunctioning.
- If no permanent DTC is output, the system is normal.
INSPECTION PROCEDURE
HINT
- The monitor for this DTC detects when the timing chain is shifted by one tooth or more.
- Read freeze frame data using the Techstream. 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.
- 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 ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0016 OR P0018)
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).

DTC P0016 or P0018 is output when foreign objects in engine oil are caught in some parts of the system. These codes 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, thus eliminating the source of the problem.
