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:

(a)

It takes 5 seconds or more to change the valve timing by 5°CA.

(b)

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.

CAUTION / NOTICE / HINT

NOTICE:
·

Vehicle Control History may be stored in the hybrid vehicle control ECU assembly if the engine is malfunctioning. Certain vehicle condition information is recorded when Vehicle Control History is stored. Reading the vehicle conditions recorded in both the Freeze Frame Data and Vehicle Control History can be useful for troubleshooting.

(Select Powertrain in Health Check and then check the time stamp data.)

·

If any "Engine Malfunction" Vehicle Control History item has been stored in the hybrid vehicle control ECU assembly, make sure to clear it. However, as all Vehicle Control History items are cleared simultaneously, if any Vehicle Control History items other than "Engine Malfunction" are stored, make sure to perform any troubleshooting for them before clearing Vehicle Control History.

HINT:
·

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.
