MONITOR STRATEGY

TYPICAL ENABLING CONDITIONS

CONFIRMATION DRIVING PATTERN

INSPECTION PROCEDURE

CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO P0016 OR P0017)

PERFORM ACTIVE TEST USING GTS (OPERATE CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY)

CHECK ENGINE MECHANICAL SYSTEM

INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY (FOR INTAKE OR EXHAUST SIDE)

INSPECT OIL CONTROL VALVE FILTER

REPLACE CAMSHAFT TIMING GEAR ASSEMBLY OR CAMSHAFT TIMING EXHAUST GEAR ASSEMBLY

CHECK WHETHER DTC OUTPUT RECURS (DTC P0016 OR P0017)

DESCRIPTION

MONITOR DESCRIPTION

1. 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 specified range in consecutive driving cycles, the ECM illuminates the MIL and stores DTC P0016.
   
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 specified range in consecutive driving cycles, the ECM illuminates the MIL and stores DTC P0017.

TYPICAL ENABLING CONDITIONS

CONFIRMATION DRIVING PATTERN

1. Connect the GTS to the DLC3.
   
2. Turn the ignition switch to ON and turn the GTS on.
   
3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
   
4. Turn the ignition switch off and wait for at least 30 seconds.
   
5. Turn the ignition switch to ON and turn the GTS on [A].
   
6. Start the engine and warm it up until the engine coolant temperature reaches 75°C (167°F) or higher [B].
   
7. Idle the engine for 5 minutes or more [C].
   
8. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [D].
   
9. Read the pending DTCs.
   

   HINT:

   1. If a pending DTC is output, the system is malfunctioning.
      
   2. If a pending DTC is not output, perform the following procedure.
      
10. Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
    
11. Input the DTC: P0016 or P0017.
    
12. 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

    HINT:

    1. If the judgment result shows NORMAL, the system is normal.
       
    2. If the judgment result shows ABNORMAL, the system has a malfunction.
       
    3. If the judgment result shows INCOMPLETE or N/A, perform steps [E] through [G].
       
13. Drive the vehicle for 2 to 3 minutes [E].
    

    CAUTION:

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

14. Idle the engine for 5 minutes or more [F].
    
15. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [G].
    
16. Read the pending DTCs.
    

    HINT:

    1. If a pending DTC is output, the system is malfunctioning.
       
    2. If a pending DTC is not output, perform the following procedure.
       
17. Check the DTC judgment result.
    

    HINT:

    1. If the judgment result shows NORMAL, the system is normal.
       
    2. If the judgment result shows ABNORMAL, the system has a malfunction.
       

INSPECTION PROCEDURE

HINT:

Read freeze frame data using the GTS. 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.

1. Connect the GTS to the DLC3.
   

2. Turn the ignition switch to ON.
   

3. Turn the GTS on.
   

4. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
   

5. Read the DTCs.
   
   

   Result

   Result	Proceed to
   DTC P0016 or P0017 is output	A
   DTC P0016 or P0017 and other DTCs are output	B

   HINT:

   If any DTCs other than P0016 or P0017 are output, troubleshoot those DTCs first.

HINT:

If the VVT system can be operated through the Active Test, it can be assumed that the VVT system is operating normally.

1. Connect the GTS to the DLC3.
   

2. Start the engine.
