Diagnostic Aids
- Ensure that the fuel level is in the same range as the customer concern.
- For intermittent diagnosis, refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
- Refer to Fuel Level Specifications in order to verify the correct fuel level sensor readings. The Fuel Level Sensor parameter is available on the scan tool in the engine control module (ECM)/powertrain control module (PCM) Data list.
