P0746 — Pressure-control solenoid — performance or stuck off

P0746: Pressure-control solenoid — performance or stuck off — what it means, the affected system and what to check before replacing parts.

Meaning, symptoms, causes and checks

The transmission monitor reports an unsatisfactory pressure-control response or a function remaining OFF when expected to respond. The label 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

  • Delayed shifts; vibration and transmission limp mode.

Possible causes

  • Stuck/faulty solenoid A, low/contaminated ATF or damaged wiring.

What to check

  • Inspect fluid and solenoid A connections; check its hydraulic operation.

Also written as: P0746-00, P074600, PO746 (some scan tools add the fault-type byte, e.g. -00).
