MONITOR DESCRIPTION
The ECM optimizes the exhaust valve timing using the Variable Valve Timing (VVT) system to control the exhaust camshaft. The VVT system includes the ECM, cam timing oil control solenoid assembly, camshaft timing gear bolt (camshaft timing oil control valve assembly [for exhaust camshaft]) and camshaft timing exhaust gear assembly. The ECM sends a target duty-cycle control signal to the cam timing oil control solenoid assembly. The camshaft timing gear bolt (camshaft timing oil control valve assembly [for exhaust camshaft]) is operated to control the oil pressure supplied to the camshaft timing exhaust gear assembly based on this signal. The camshaft timing exhaust gear assembly can advance or retard the exhaust camshaft.
If the difference between the target and actual exhaust valve timing is large, and changes in the actual exhaust valve timing are small, the ECM interprets this as the camshaft timing exhaust gear assembly stuck malfunction and stores a DTC.
- Example:
-
A DTC is stored when the following conditions are met:
- It takes 5 seconds or more to change the valve timing by 5°CA.
- After the above condition is met, the cam timing oil control solenoid is forcibly activated for 9.5 seconds.
DTC P001400 and P002400 (Advanced Camshaft Timing) is subject to 2 trip detection logic.
DTC P001500 and P002500 (Retarded Camshaft Timing) is subject to 1 trip detection logic.
These DTCs indicate that the camshaft timing exhaust gear assembly cannot operate properly due to a camshaft timing gear bolt (camshaft timing oil control valve assembly [for exhaust camshaft]) malfunction or the presence of foreign matter in the camshaft timing gear bolt (camshaft timing oil control valve assembly [for exhaust camshaft]).

TYPICAL MALFUNCTION THRESHOLDS
P0014 and P0024: Advanced Camshaft Timing
|
Both of the following conditions are met |
- |
|
Deviation of actual valve timing and target valve timing |
More than 5°CA (Crankshaft Angle) for 5 seconds or more after the VVT hold duty ratio learned value reaches the upper or lower limit. |
|
Valve timing |
No change at advanced valve timing |
P0015 and P0025: Retarded Camshaft Timing
|
Both of the following conditions are met |
- |
|
Deviation of actual valve timing and target valve timing |
More than 5°CA (Crankshaft Angle) for 5 seconds or more after the VVT hold duty ratio learned value reaches the upper or lower limit. |
|
Valve timing |
No change at retarded valve timing |
If the difference between the target and actual camshaft timing is greater than the specified value, the ECM operates the VVT actuator for 10 seconds by applying and releasing oil pressure. Then, the ECM monitors the camshaft timing change for 10 seconds.

CONFIRMATION DRIVING PATTERN
HINT:
-
After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
Click here
-
When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
Click here
- Connect the Techstream to the DLC3.
- Turn the engine switch on (IG).
- Turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the engine switch off and wait for at least 30 seconds.
- Turn the engine switch on (IG) [A].
- Turn the Techstream on.
- Start the engine and warm it up until the engine coolant temperature reaches 75°C (167°F) or higher [B].
-
Drive the vehicle at approximately 60 km/h (37 mph) for 10 minutes or more [C].
CAUTION:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
- Idle the engine for 3 minutes or more [D].
- Enter the following menus: Powertrain / Engine / Trouble Codes [E].
-

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.
- DTC P001400, P001500, P002400 or P002500 may be stored when foreign matter in the engine oil is caught in some parts of the system. The DTC will remain stored even if the system returns to normal after a short time. This foreign matter may then be captured by the oil filter.
- 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.
