DTC P0967
DTC P0967: CVT Driven Pulley Pressure Control Valve Circuit High
General Description
The CVT driven pulley pressure control solenoid valve controls hydraulic pressure to the driven pulley. The CVT driven pulley pressure control solenoid valve is controlled by duty cycle output. The spool in the CVT driven pulley pressure control solenoid valve moves the valve according to the current, and produces hydraulic pressure in proportion to the current. The powertrain control module (PCM) measures the current that passes through the CVT driven pulley pressure control solenoid valve 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, the PCM detects a malfunction (open, short to ground) and stores a DTC.

[ ]: HDS Parameter
Malfunction Threshold
The measured current for the PCM's command value is as specified here for at least 1 second.
| Duty (%) | Current (A) | Failure mode |
|---|---|---|
| Less than 13.7 | More than 0.58 | High Input |
| 13.7 - 21.1 | More than 0.89 | High Input |
Possible Cause
NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
- CVT driven pulley pressure control solenoid valve DNLS line short to power
- CVT driven pulley pressure control solenoid valve DNLS line short to ground
- CVT driven pulley pressure control solenoid valve internal circuit short
- PCM internal circuit failure
Confirmation Procedure
Operating Condition
Start the engine, and wait for at least 1 second.
With the HDS
None.
Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected, the MIL comes on and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the PCM memory.
Conditions for clearing the DTC
The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the 12 volt battery.
