Hydraulic Pressure Sensor Circuit
What it means
P0932 means the transmission control module has flagged a fault in the hydraulic pressure sensor circuit — the sensor that reports the pressure driving the transmission's hydraulic controls. The engine still starts and runs, but without a trustworthy pressure reading the transmission may shift inaccurately, slip, or run hot. Because a low or wrong fluid level can also affect pressure, checking the fluid is a sensible first step.
Can I keep driving? The engine starts and runs, but the transmission may shift inaccurately, slip, or run hot; drive gently and get it checked soon to protect the transmission.
Common symptoms
What you'll notice
- Check-engine light on
- Transmission shifts inaccurately or not at all
- Slipping or reduced performance
- Transmission running hot
Common causes
Most likely first
- Faulty hydraulic pressure sensorLikely
- Wiring or connector problems in the sensor circuitCommon
- Incorrect transmission/hydraulic fluid levelCommon
- Failed transmission control module (TCM)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and check the transmission/hydraulic fluid level and condition first.
- Inspect the pressure-sensor connector and wiring for damage, corrosion, opens, or shorts.
- Compare the sensor's signal voltage against service data; replace the hydraulic pressure sensor if out of range.
- If wiring and sensor are good, suspect the TCM. Clear and re-test.
