Circuit/System Testing
NOTE:
If equipped, the following tests can be performed at an inline connector. See schematics for the corresponding terminals to test at.
- Ignition OFF, disconnect the harness connector at the fuel level sensor.
- Ignition ON, verify the Fuel Tank Level remaining parameter is 4 percent or less.
- If greater than the specified range, test the signal circuit terminal B for a short to ground. If the circuit tests normal, replace the ECM.
- If all circuits test normal, perform the fuel level sensor component test before replacing the fuel level sensor.
