What Does P0967 Mean?
The TCM has detected that the Pressure Control Solenoid B (PCS-B) circuit voltage is consistently higher than the commanded level, pointing to a short to battery voltage or an open in the solenoid ground path. The solenoid is being held energized or de-energized contrary to TCM commands, resulting in abnormal transmission line pressure. Symptoms typically include very soft or slipping shifts if pressure is too low, or the transmission may enter limp mode.
Safety Warning
If the solenoid is stuck energized, low line pressure can cause clutch slippage and rapid overheating, potentially leading to transmission failure. Discontinue driving if slipping is observed and have the vehicle towed to a repair facility.
Common Causes
35%
Open or high-resistance ground path in the PCS-B circuit
25%
Short to battery voltage in the PCS-B wiring harness
20%
Corroded or backed-out ground terminal at the transmission case connector
15%
PCS-B solenoid with open ground-side winding
5%
TCM solenoid driver stuck in the high state
Diagnostic Steps
1
Measure PCS-B solenoid resistance at the transmission connector — should be within specification. An extremely high or open reading may indicate an open ground leg within the solenoid.
2
With the transmission connector disconnected, check for battery voltage on the PCS-B control wire at the TCM output. Constant battery voltage with no solenoid load suggests a TCM driver fault or a short to B+ in the harness.
3
Verify ground path continuity from the PCS-B ground pin through the internal harness, case connector, external harness, and back to the TCM ground reference. Any interruption causes a high circuit condition.
4
Inspect the transmission case connector ground pins for corrosion, looseness, or being backed out of the connector body.
5
If all tests are within specification, use the scan tool to command PCS-B on and off while monitoring circuit voltage at the TCM connector to confirm proper driver operation.

The most common cause of P0967 (Pressure Control Solenoid "B" Control Circuit High) is: Open or high-resistance ground path in the PCS-B circuit
Typical repair costs for P0967 range from $200 to $1,400, depending on the vehicle, location, and whether you do it yourself or go to a shop.
If the solenoid is stuck energized, low line pressure can cause clutch slippage and rapid overheating, potentially leading to transmission failure. Discontinue driving if slipping is observed and have the vehicle towed to a repair facility.
