Fuel Gage Inaccurate or Inoperative

FUEL GAGE INACCURATE OR INOPERATIVE

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. Component Tests and General Diagnostics
- Refer to Fuel Level Specifications in order to verify the correct fuel level sensor readings. The Fuel Level (%) parameter is available on the scan tool in the engine control module (ECM)/powertrain control module (PCM) evaporative emission (EVAP) data list.

TEST DESCRIPTION

Step 1 - Step 5:

Step 6 - Step 13:

The numbers below refer to the step numbers in the diagnostic table.
3. This step tests for a high resistance in the signal circuit and the sensor ground circuit of the fuel level sensor.
13. DTCs will set in the ECM/PCM when you perform this diagnostic table.
