DTC P0966: CVT Driven Pulley Pressure Control Valve Circuit Low Voltage




General Description
The CVT driven pulley pressure control valve controls hydraulic pressure to the driven pulley. The spool in the linear solenoid pushes the valve by duty cycle according to the current, and produces hydraulic pressure in proportion to the current. The CVT driven pulley pressure control valve measures the current that passes through the linear solenoid and uses feedback control to compensate for the difference between the measured current and the commanded one. If the measured current is not equal to the duty cycle command, a malfunction (open, short to ground) is detected and a DTC is stored.

Diagnosis Details

Conditions for illuminating the MIL
When a malfunction is detected, the MIL comes on and the DTC and the freeze frame data are stored in the PCM memory.

Conditions for clearing the MIL
The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic runs.

The MIL, the DTC, and the freeze frame data can be cleared by using the scan tool Clear command or by disconnecting the battery.
