P0795 — Pressure-control solenoid C — malfunction

P0795: Pressure-control solenoid C — malfunction — what it means, the affected system and what to check before replacing parts.

Meaning, symptoms, causes and checks

The transmission monitor reports a general fault associated with the pressure-control solenoid. The label C identifies the monitored function; it does not establish the valve location or prove the solenoid itself needs replacement.

Affected system: Transmission hydraulic pressure control

Symptoms

  • Warning light may illuminate
  • Related system function may be impaired
  • Vehicle-specific symptoms vary

Possible causes

  • Transmission fluid, hydraulic, solenoid, connector, or control-circuit issue
  • Related wiring, connector, power or ground fault
  • Vehicle-specific mechanical or control issue

What to check

  • Record stored and pending codes and freeze-frame data
  • Compare commanded and actual transmission data, inspect fluid condition and level according to the vehicle procedure, then test the relevant circuit and solenoid.
  • Confirm measured values against the vehicle service information
  • Retest under the conditions that set the code
  • Compare commanded and actual transmission data, inspect fluid condition and level according to the vehicle procedure, then test the relevant circuit and solenoid.
  • Repair the verified cause and confirm the code does not return

Also written as: P0795-00, P079500, PO795 (some scan tools add the fault-type byte, e.g. -00).
