Fuel Level Sensor A Stuck

Where it lives

For P25B0, the description names the sensor as the part involved.

Check these first

• Fuel level sender A stuck on its float arm
• Dirty or worn sender resistor track
• Wiring fault between the tank sender and the module
• Sender A reading frozen while fuel is added
• Incorrect sender calibration after replacement

What to do next

1. Compare fuel level sensor A to sensor B live data
2. Add fuel and watch sender A respond
3. Inspect the sender A connector and wiring
4. Test sender A resistance through its travel
5. Replace fuel level sender A if the signal stays frozen
6. Clear the code and retest
