Engine Disconnect Clutch Pressure Sensor Circuit Range/Performance

Where it lives

For P28F2, the description names the sensor as the part involved.

Check these first

• An engine disconnect clutch pressure sensor reading outside its range
• A contaminated engine disconnect clutch pressure sensor
• High resistance in the engine disconnect clutch pressure sensor circuit
• A failed engine disconnect clutch pressure sensor
• A drifting engine disconnect clutch apply pressure

What to do next

1. Read engine disconnect clutch pressure sensor voltage on a scan tool
2. Compare the disconnect clutch pressure sensor to a known good reading
3. Test the disconnect clutch pressure sensor circuit for added resistance
4. Check transmission fluid level and condition
5. Replace the disconnect clutch pressure sensor if the reading stays skewed
6. Clear the code and retest
