| DTC Code | DTC Name |
|---|---|
| P001100 | Camshaft Position "A" - Timing Over-Advanced or System Performance Bank 1 |
| P001200 | Camshaft Position "A" - Timing Over-Retarded Bank 1 |
DESCRIPTION
Refer to DTC P001013.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Memory | Note |
|---|---|---|---|---|---|---|
| P001100 | Camshaft Position "A" - Timing Over-Advanced or System Performance Bank 1 | Intake valve timing is stuck at a certain value when in the advance range (1 trip detection logic). |
|
Comes on | DTC stored | SAE Code: P0011 |
| P001200 | Camshaft Position "A" - Timing Over-Retarded Bank 1 | Intake valve timing is stuck at a certain value when in the retard range (2 trip detection logic). |
|
Comes on | DTC stored | SAE Code: P0012 |
MONITOR DESCRIPTION
The ECM optimizes the intake valve timing using the Variable Valve Timing (VVT) system to control the intake camshaft. The VVT system includes the ECM, camshaft timing oil control valve assembly and VVT controller (camshaft timing gear assembly). The ECM sends a target duty-cycle control signal to the camshaft timing oil control valve assembly. This control signal regulates the oil pressure supplied to the VVT controller. The VVT controller can advance or retard the intake camshaft.
If the difference between the target and actual intake valve timing is large, and changes in the actual intake valve timing are small, the ECM interprets this as a VVT controller 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 camshaft timing oil control valve assembly is forcibly activated for 9.5 seconds or more.
DTC P001100 (Advanced Camshaft Timing) is subject to 1 trip detection logic.
DTC P001200 (Retarded Camshaft Timing) is subject to 2 trip detection logic.
These DTCs indicate that the VVT controller cannot operate properly due to a camshaft timing oil control valve assembly malfunction or the presence of foreign matter in the camshaft timing oil control valve assembly.

CONFIRMATION DRIVING PATTERN
Connect the GTS to the DLC3.
Turn the power switch on (IG).
Turn the GTS on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Tech Tips
If P001100 was output:
Clear the DTC without using the GTS.
If P001200 was output:
Clear the DTC using the GTS.
Turn the power switch off and wait for at least 30 seconds.
Turn the power switch on (IG) [A].
Turn the GTS on.
Put the engine in Inspection Mode (Maintenance Mode).
Start the engine and warm it up until the engine coolant temperature is 75°C (167°F) or higher [B].
With the engine running, accelerate the vehicle to 75 km/h (46 mph) or more by depressing the accelerator pedal for 10 seconds or more [C].
CAUTION:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
Tech Tips
If the engine stops, further depress the accelerator pedal to restart the engine.
Idle the engine for 100 seconds or more [D].
Enter the following menus: Powertrain / Engine / Trouble Codes [E].
Read the pending DTCs.
Tech Tips
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 / Utility / All Readiness.
Input the DTC: P001100 or P001200.
Check the DTC judgment result.
| GTS Display | Description |
|---|---|
| NORMAL |
|
| ABNORMAL |
|
| INCOMPLETE |
|
| N/A |

Tech Tips
If the judgment result is NORMAL, the system is normal.
If the judgment result is ABNORMAL, the system is malfunctioning.
If the judgment result is INCOMPLETE or N/A, perform steps [F] through [H].
With the engine running, accelerate the vehicle to 75 km/h (46 mph) or more by depressing the accelerator pedal for 10 seconds or more [F].
CAUTION:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
Tech Tips
If the engine stops, further depress the accelerator pedal to restart the engine.
Idle the engine for 100 seconds or more [G].
Enter the following menus: Powertrain / Engine / Trouble Codes [H].
Read the pending DTCs.
Tech Tips
If a pending DTC is output, the system is malfunctioning.
If a pending DTCs are not output, perform the following procedure.
Check the DTC judgment result again.
Tech Tips
If the judgment result is NORMAL, the system is normal.
If the judgment result is ABNORMAL, the system is malfunctioning.
CAUTION / NOTICE / HINT
Tech Tips
DTC P001100 or P001200 may be stored when foreign matter in the engine oil is caught in parts of the system. The DTC will remain stored even if the system returns to normal after a short time. The foreign matter may then be captured by the oil filter.
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.
PROCEDURE
CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P001100 OR P001200)
Connect the GTS to the DLC3.
Turn the power switch on (IG).
Turn the GTS on.
Enter the following menus: Powertrain / Engine / Trouble Codes.
Read the DTCs.
