| 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 (1 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, cam timing oil control solenoid assembly (for intake camshaft), camshaft timing gear bolt (camshaft timing oil control valve assembly [for intake camshaft]) and camshaft timing gear assembly. The ECM sends a target duty-cycle control signal to the cam timing oil control solenoid assembly (for intake camshaft). The camshaft timing gear bolt (camshaft timing oil control valve assembly [for intake camshaft]) is operated to control the oil pressure supplied to the camshaft timing gear assembly based on this signal. The camshaft timing gear assembly 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 the camshaft timing gear assembly stuck malfunction and stores a DTC.
Example:
DTC P001100 is stored when the following conditions are met:
It takes 5 seconds or more for intake valve timing to change 5 deg(CA).
After the malfunction condition above has been detected, the same condition continues 9.5 seconds or more.
DTC P001200 is stored when the following conditions are met:
It takes 5 seconds or more for intake valve timing to change 5 deg(CA).
After the malfunction condition above has been detected, the same condition continues 60 seconds or more.
These DTCs indicate that the camshaft timing gear assembly cannot operate properly due to a camshaft timing gear bolt (camshaft timing oil control valve assembly [for intake camshaft]) malfunction or the presence of foreign matter in the camshaft timing gear bolt (camshaft timing oil control valve assembly [for intake camshaft]).

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).
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 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].
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 P0001200.
Check the DTC judgment result.
| GTS Display | Description |
|---|---|
| NORMAL |
|
| ABNORMAL |
|
| INCOMPLETE |
|
| N/A |
|
Tech Tips
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 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.
Tech Tips
Depress the accelerator pedal by a large amount.
Idle the engine for 3 minutes 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 DTC is not output, perform the following procedure.
Check the DTC judgment result again.
Tech Tips
If the judgment result shows NORMAL, the system is normal.
If the judgment result shows ABNORMAL, the system has a malfunction.
CAUTION / NOTICE / HINT
Tech Tips
DTC P001100 or P001200 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. That 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 ignition switch to ON.
Turn the GTS on.
Enter the following menus: Powertrain / Engine / Trouble Codes.
Read the DTCs.

Tech Tips
If any DTCs other than P001100 or P001200 are output, troubleshoot those DTCs first.
