P001200 Camshaft Position “A” – Timing Over-Retarded Bank 1
DESCRIPTION
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Memory | Note |
|---|---|---|---|---|---|---|
| P001200 | Camshaft Position “A” – Timing Over-Retarded Bank 1 | With engine warmed up and while driving in urban area (engine speed 4000 rpm or less), intake side valve timing does not change in retarded position, and target and actual valve timing do not match (1 trip detection logic). | · Camshaft timing gear assembly·Cam timing control motor with EDU assembly·ECM | Comes on | DTC stored | SAE Code: P0012 |
MONITOR DESCRIPTION
This DTC is output when a valve timing stuck condition is detected. With the engine speed at 4000 rpm or less in the retard angle position, if the valve timing does not vary, and there is a large difference in the target and actual valve timing, it is determined that a malfunction has occurred. When this malfunction is detected, the ECM will illuminate the MIL and store this DTC.
CONFIRMATION DRIVING PATTERN
1. Connect the GTS to the DLC3.
2. Turn the power switch on (IG).
3. Turn the GTS on.
4. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
5. Turn the power switch off and wait for at least 30 seconds.
6. Turn the power switch on (IG) [A].
7. Turn the GTS on.
8. Put the engine in Inspection Mode (Maintenance Mode).
9. Start the engine and warm it up until the engine coolant temperature reaches 75°C (167°F) or higher [B].
10. With the engine running, 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.
HINT:
If the engine stops, further depress the accelerator pedal to restart the engine.
11. Idle the engine for 3 minutes or more [D].
12. Enter the following menus: Powertrain / Engine / Trouble Codes [E].
13. 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.
14. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
15. Input the DTC: P001200.
16. 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 |
HINT:
· If the judgment result is NORMAL, the system is normal.
· If the judgment result is ABNORMAL, the system has a malfunction.
· If the judgment result is INCOMPLETE, perform steps [F] through [H].
17. With the engine running, repeat the pattern of accelerating the vehicle from rest to approximately 60 km/h (37 mph) and then decelerating the vehicle 10 to 15 times [F].
CAUTION:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
HINT:
· If the engine stops, further depress the accelerator pedal to restart the engine.
· Depress the accelerator pedal by a large amount.
18. Idle the engine for 3 minutes or more [G].
19. Enter the following menus: Powertrain / Engine / Trouble Codes [H].
20. 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.
21. Check the DTC judgment result again.
HINT:
· If the judgment result is NORMAL, the system is normal.
· If the judgment result is ABNORMAL, the system has a malfunction.
