Fuel Level Sensor A Circuit Low

Where it lives

For P0462, the circuit described runs through the sensor. The description of P0462 reports a fault at the sensor.

Check these first

• A fuel level sensor A reading low
• A short to ground on the sender signal wire
• Corrosion in the sender connector
• A sender float stuck at the bottom
• An ECM reference voltage fault

What to do next

1. Read the fuel level sender voltage on a scan tool
2. Check the sender signal wire for a short to ground
3. Inspect the sender connector for corrosion
4. Check the float for sticking at the bottom
5. Replace the sender if the voltage stays low
6. Clear the code and retest
