Monitor description
The ecm optimizes the valve timing using the variable valve timing (vvt) system to control the intake valve camshaft. The vvt system includes the ecm, the oil control valve (ocv) and the vvt controller. The ecm sends a target ”duty–cycle” control signal to the ocv. This control signal, applied to the ocv, regulates the oil pressure supplied to the vvt controller. The vvt controller can advance or retard the intake valve camshaft.
The ecm calibrates the valve timing of the vvt system by setting the camshaft to the maximum retard angle when the engine speed is idling. The ecm closes the ocv to retard the cam. The ecm stores this valve as ”vvt learned value” (when the difference between the target valve timing and the actual valve timing is 5 or less, the ecm learns it).
If the learned value meets both of the following conditions (”a” and ”b”), the ecm interprets this as a defect in the vvt system and set a dtc.
- ”vvt learning” value is less than 24 ca, or more than 46 ca.
- above condition continues for more than 18 seconds.
