Fuel Level Sensor C Stuck

Where it lives

For P25DC, the description names the sensor as the part involved.

Check these first

• A fuel level sensor C float stuck against the tank baffle
• A seized float pivot on the sensor C assembly
• A worn resistance track holding one reading
• A bent float arm on the sensor C unit

What to do next

1. Read fuel level sensor C voltage on a scan tool while rocking the vehicle
2. Compare sensor C reading before and after adding fuel
3. Inspect the sensor C float and pivot for binding
4. Check the sensor C wiring for a shorted signal
5. Replace the stuck fuel level sensor C sender if the wiring tests good
6. Clear the code and retest
