Fuel Level Sensor B Performance

Where it lives

For P2066, the part to look at first is the sensor named here.

Check these first

• A fuel level sensor B reading that drifts from the actual fuel level
• High resistance in the sensor B circuit
• A sticking fuel level sensor B float
• A corroded sensor B connector

What to do next

1. Read fuel level sensor B on a scan tool
2. Compare the sensor B reading to the actual fuel level
3. Add a known amount of fuel and recheck the reading
4. Test the sensor B circuit for added resistance
5. Replace the fuel level sensor B if the reading stays off
6. Clear the code and retest
