P0795 Pressure Control Solenoid C Malfunction

P0795 indicates a pressure control solenoid C malfunction. The controller detected a fault in the solenoid C control path or pressure response.

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 major transmission parts until the pressure-control command and circuit are tested.

Symptoms of P0795

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 P0795

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

Monitor solenoid C command, line-pressure data, shift timing, slip, input speed, output speed, and fluid temperature.
Inspect solenoid wiring, internal harness, case connector, connector fluid intrusion, solenoid resistance, and driver circuit behavior.
Review related ratio, pressure-control, and fluid-temperature codes to determine whether the fault is electrical or hydraulic.
