DESCRIPTION

Tip:

If DTC P0014 or P0015 is output, check the VVT (Variable Valve Timing) system.

Refer to DTC P0013 (Click here).

CONFIRMATION DRIVING PATTERN

Connect the GTS to the DLC3.
Turn the ignition switch to ON and turn the GTS on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure) (Click here).
Turn the ignition switch off and wait for at least 30 seconds.
Turn the ignition switch to ON and turn the GTS on [A].
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 37 mph (60 km/h) 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 and ECT / Trouble Codes [E].
Read the pending DTCs.
Tip:
- 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: P0014 or P0015.

Check the DTC judgment result.


GTS 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

Tip:

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 [F] through [H].

Repeat the pattern of accelerating the vehicle from rest to approximately 37 mph (60 km/h) and then decelerating the vehicle 10 to 15 times [F].

CAUTION:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.

Tip:
Depress the accelerator pedal by a large amount.
Idle the engine for 3 minutes or more [G].
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [H].
Read the pending DTCs.
Tip:
- 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 again.
Tip:
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.

CAUTION / NOTICE / HINT

Tip:

Read freeze frame data using the GTS. Freeze frame data records the engine conditions 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.

PROCEDURE

CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0014 OR P0015)

Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

Read the DTCs.

Table 1. Result
Result	Proceed to
DTC P0014 or P0015 is output	A
DTC P0014 or P0015 and other DTCs are output	B

Tip:

If any DTCs other than P0014 or P0015 are output, troubleshoot those DTCs first.

INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY (FOR EXHAUST SIDE)
1. Inspect the camshaft timing oil control valve assembly (for exhaust side) (Click here).
REPLACE CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY (FOR EXHAUST SIDE)

(Click here)
INSPECT CAMSHAFT TIMING EXHAUST GEAR ASSEMBLY
1. Inspect the Camshaft timing exhaust gear assembly (Click here).
  
  Tip:
  Perform "Inspection After Repair" after replacing the camshaft timing exhaust gear assembly (Click here).
REPLACE CAMSHAFT TIMING EXHAUST GEAR ASSEMBLY

CHECK ENGINE MECHANICAL SYSTEM
1. Check for mechanical malfunctions that affect the valve timing, such as a jumped tooth or stretching of the timing chain (Click here).
REPAIR OR REPLACE MALFUNCTIONING PARTS, COMPONENT AND AREA

CHECK WHETHER DTC OUTPUT RECURS (DTC P0014 OR P0015)

Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Clear the DTCs (Click here).
Turn the ignition switch off and wait for at least 30 seconds.
Turn the ignition switch to ON and turn the GTS on.
Start the engine and warm it up.
Drive the vehicle in accordance with the driving pattern described in the Confirmation Driving Pattern.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

Read the DTCs.

Table 2. Result
Result	Proceed to
DTC is not output	A
DTC P0014 or P0015 is output	B

Tip:

DTC P0014 or P0015 is output when foreign objects in engine oil are caught in some parts of the system. These codes will remain stored for a short time even after the system returns to normal. These foreign objects are then captured by the oil filter, thus eliminating the source of the problem.
