Hydraulic Pressure Sensor Circuit
- Severity
- High
- Driving
- Drive only to a garage
A fault in the hydraulic pressure sensor circuit. On an automated manual transmission an electric pump keeps an accumulator charged with hydraulic pressure, and that pressure is what moves the clutch and selector actuators. This sensor tells the module how much pressure is available; without it the module cannot know whether it can complete a gear change.
Possible causes
- CommonFailed hydraulic pressure sensor
- CommonCorroded or damaged connector at the hydraulic unit
- CommonWiring damage in the harness
- PossibleLoss of reference voltage or earth
- PossibleFluid leak contaminating the connector
- RareFailed control module input
What you might notice
- Transmission will not change gear
- Car stuck in neutral or will not move
- Hydraulic pump running constantly
- Transmission warning message
- Check engine light on
What to check, in order
- Watch the reported hydraulic pressure on the live data screen while the pump runs. A reading that does not change identifies the fault.
- Check the reference voltage and earth at the sensor.
- Inspect the connector at the hydraulic unit for corrosion and fluid contamination.
- Check the hydraulic fluid level and look for leaks around the unit.
- Read all codes - a pump relay or pressure unit code alongside this one changes the diagnosis.
