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, 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. 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.

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]).

Battery voltage	11 V or higher
Engine speed	400 to 4000 rpm
Engine coolant temperature	75 to 100°C (167 to 212°F)

TYPICAL MALFUNCTION THRESHOLDS

P0011 and P0021: Advanced Camshaft Timing

Both of the following conditions are met	-
Deviation of actual valve timing and target valve timing	More than 5°CA (Crankshaft Angle) for 5 seconds or more after the VVT hold duty ratio learned value reaches the upper or lower limit.
Valve timing	No change at advanced valve timing

P0012 and P0022: Retarded Camshaft Timing

Both of the following conditions are met	-
Deviation of actual valve timing and target valve timing	More than 5°CA (Crankshaft Angle) for 5 seconds or more after the VVT hold duty ratio learned value reaches the upper or lower limit.
Valve timing	No change at retarded valve timing

If the difference between the target and actual camshaft timing is greater than the specified value, the ECM operates the VVT actuator for 10 seconds by applying and releasing oil pressure. Then, the ECM monitors the camshaft timing change for 10 seconds.
