P0969 Pressure Control Solenoid C Control Circuit Range/Performance

P0969 indicates range or performance trouble in pressure control solenoid C control circuit. The command or pressure response is outside the expected window.

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 assume the solenoid coil is electrically bad; performance faults can be hydraulic, fluid-related, or mechanical.

Symptoms of P0969

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 P0969

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

Compare commanded pressure, solenoid C duty cycle, actual or inferred pressure, shift timing, and slip data.
Inspect fluid condition, connector fit, internal harness, valve-body sticking, and solenoid response.
Check whether the fault appears hot, cold, under high load, or during specific shift events.
