MONITOR 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 (for intake side) and the camshaft timing gear assembly.
The ECM sends a target duty-cycle control signal to the camshaft timing oil control valve assembly (for intake side). This control signal regulates the oil pressure applied to the camshaft timing gear assembly. The camshaft timing gear assembly can advance or retard the intake camshaft. The ECM calibrates the intake valve timing by setting the intake camshaft to the most retarded angle while the engine is idling. The ECM closes the camshaft timing oil control valve assembly (for intake side) to retard the cam. The ECM stores this value as the VVT learning value. When the difference between the target and actual intake valve timing is 5°CA (crankshaft angle) or less, the ECM stores it.
If the VVT learning value matches the following conditions, the ECM determines the existence of a malfunction in the VVT system, and stores the DTC.
- The VVT learning value: Less than 18.5°CA, or more than 43.5°CA.
- The above condition continues for 18 seconds or more.
This DTC indicates that the intake camshaft has been installed toward the crankshaft at an incorrect angle, caused by factors such as the timing chain having jumped a tooth.
This monitor begins to run after the engine has idled for 5 minutes.

Clear DTCs (even if no DTCs are stored, perform the clear DTC procedure) (See page
).
- Turn the ignition switch off and wait for at least 30 seconds.
- Turn the ignition switch to ON and turn the Techstream on [A].
- Start the engine and warm it up until the engine coolant temperature reaches 75°C (167°F) or more [B].
- Idle the engine for 5 minutes or more [C].
- Enter the following menus: Powertrain / Engine / Trouble Codes [D].

- Enter the following menus: Powertrain / Engine / Utility / All Readiness.
- Input the DTC: P0016 or P0018.
-
Check the DTC judgment result.

- Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit
HINT:
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the 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 / Trouble Codes [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.
-
If the test result is INCOMPLETE or N/A and no pending DTC is output, perform a universal trip and check for permanent DTCs (See page
).
HINT:
- If a permanent DTC is output, the system is malfunctioning.
- If no permanent DTC is output, the system is normal.
CAUTION / NOTICE / HINT
HINT:
-
Bank 1 refers to the bank that includes the No. 1 cylinder*.
*: The No. 1 cylinder is the cylinder which is farthest from the transaxle.
- Bank 2 refers to the bank that does not include the No. 1 cylinder.
- 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.
