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 solenoid assembly, 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 camshaft timing oil control solenoid assembly. 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:
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 solenoid assembly is forcibly activated for 9.5 seconds.
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]).

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].
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].
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
Depress the accelerator pedal by a large amount.
Idle the engine for 3 minutes or more [G].

Read the pending DTCs.
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.
If the judgment result is NORMAL, the system is normal.
If the judgment result is ABNORMAL, the system has a malfunction.
Refer to DTC P001013.

|---|---|---|
| Bank 1 | P001100 | P001200 |
| Bank 2 | P002100 | P002200 |
If DTC P001100 or P001200 is output, check the VVT system (for intake camshaft of bank 1) circuit.
If DTC P002100 or P002200 is output, check the VVT system (for intake camshaft of bank 2) circuit.
Bank 1 refers to the bank that includes the No. 1 cylinder*.
*: The No. 1 cylinder is the cylinder which is farthest from the transmission.
Bank 2 refers to the bank that does not include the No. 1 cylinder.
DTC P001100, P001200, P002100 or P002200 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.
