瀚慖f the fuel level gauge does not sweep, replace the P16 Instrument Cluster.

3. Command the All Indicators test ON and OFF with the scan tool, verify that the low fuel level indicator turns ON and OFF.

瀚慖f the low fuel level indicator always stays on or always off, replace the P16 Instrument Cluster.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the appropriate fuel level sensor.

2. Test for less than 30 ohm at the low reference circuit terminal C.

瀚慖f greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the K20

Engine Control Module.

3. Ignition ON, test for 4.8-5.2 V between the signal circuit terminal D and ground.

瀚慖f greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the K20 Engine Control

Module.

瀚慖f less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace

the K20 Engine Control Module.

4. If all circuits test normal, replace the appropriate fuel level sensor.
