Clutch A Pressure Sensor Circuit High

Where it lives

For P28CF, the sensor sits on the circuit this code reports. The description of P28CF reports a fault at the sensor.

Check these first

• A short to voltage on the clutch A pressure sensor signal wire
• An open ground on the clutch A pressure sensor reference
• A failed clutch A pressure sensor reading high
• Corrosion in the clutch A pressure sensor connector
• High clutch A fluid pressure pegging the sensor

What to do next

1. Read clutch A pressure sensor voltage on a scan tool
2. Check clutch A pressure sensor voltage with the key on and engine off
3. Test the clutch A pressure sensor signal wire for a short to voltage
4. Check the clutch A pressure sensor ground and connector
5. Replace the clutch A pressure sensor if the circuit tests good
6. Clear the code and retest
