P0968 Pressure Control Solenoid C Control Circuit/Open

P0968 points to pressure control solenoid C control circuit or open-circuit fault. The controller cannot complete the electrical path for that solenoid.

Code details

Generic OBD-II · P0

System: Transmission
Code type: Generic (SAE / ISO controlled)
Standard: SAE J2012 / ISO 15031-6

Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not replace internal transmission parts before testing the open pressure-control solenoid C circuit.

Symptoms of P0968

Harsh, delayed, or slipping shifts, or being stuck in one gear.
Check-engine light, sometimes with limp-home mode.
Flaring RPM or a shudder under load.

Common causes of P0968

Low or degraded transmission fluid.
A failing speed sensor, shift solenoid, or pressure-control circuit.
Wiring, connector, or internal hydraulic/mechanical faults.

Useful checks before replacing parts

Check pressure control solenoid C power, control wire, internal harness, case connector, and terminal tension.
Measure circuit resistance or current using service-information limits and compare with other solenoid circuits.
Review related pressure, shift, and ratio codes to understand how the open circuit affects operation.
