DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | 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 | SAE: 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 | SAE: P0012 |
MONITOR DESCRIPTION
The ECM optimizes the intake valve timing using the VVT (Variable Valve Timing) 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 (intake camshaft timing oil control valve) 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 (intake camshaft timing oil control valve) 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.
These DTCs indicate that the camshaft timing gear assembly cannot operate properly due to a camshaft timing gear bolt (intake camshaft timing oil control valve) malfunction or the presence of foreign matter in the camshaft timing gear bolt (intake camshaft timing oil control valve).

PROCEDURE
1. | CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P001100 OR P001200) |
(a) Read the DTCs.
Powertrain > Engine > Trouble Codes Result | Proceed to |
---|---|
P001100 or P001200 and other DTCs are output | A |
P001100 or P001200 is output | B |
HINT:
If any DTCs other than P001100 or P001200 are output, troubleshoot those DTCs first.
A | GO TO DTC CHART |
|
2. | PERFORM ACTIVE TEST USING GTS (CONTROL THE INTAKE VVT OCV DUTY RATIO BANK 1) |
(a) Start the engine.
(b) Read the Data List while performing the Active Test with the engine idling.

3. | CLEAR DTC |
(a) Clear the DTCs.
Powertrain > Engine > Clear DTCs(b) Turn the ignition switch off and wait for at least 30 seconds.
|
4. | CHECK WHETHER DTC OUTPUT RECURS (DTC P001100 OR P001200) |
(a) Start the engine and warm it up.
(b) Drive the vehicle in accordance with the driving pattern described in the Confirmation Driving Pattern.
(c) Read the DTCs.
Powertrain > Engine > Trouble CodesHINT:
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.

*a | Timing Mark |
*b | TDC Timing Mark |
*c | Groove |
(a) Remove the cylinder head cover sub-assembly.
(b) Turn the crankshaft pulley and align its groove with the TDC timing mark of the timing chain cover.
(c) Check that the timing marks of the camshaft timing gear assembly and camshaft timing exhaust gear assembly are at the positions shown in the illustration.
HINT:
If the timing marks are not as shown, turn the crankshaft one revolution clockwise.
OK:
Timing marks on camshaft timing gear assembly and camshaft timing exhaust gear assembly are at the positions shown in the illustration.
HINT:
If the result is not as specified, check for mechanical malfunctions that may have affected the valve timing, such as a jumped tooth or stretching of the timing chain.
