Engine Control
P0463 Fuel Level Sensor - Inspection/Repair:_:W/Harness Inspection

Terminal and Connector inspection

1. Many malfunctions in the electrical system are caused by poor harness(es) and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
3. Has a problem been found?






Signal Circuit Inspection

Voltage Check
1. IG KEY 'OFF'.
2. Disconnect the sub fuel level sender and the cluster connector.
3. IG KEY 'ON'.
4. Measure the voltage between signal terminal of Fuel Level Sender 'A' connector and chassis ground.

Specification :0V




5. Is voltage within specification?





Check for Open in Ground Circuit
1. IG KEY 'OFF'.
2. Disconnect sub fuel level sender harness connector.
3. Measure the resistance of both terminal of sub fuel level sender harness.

Specification :below 1Ohms




4. Is the resistance within specification?






Ground Circuit Inspection

Check open in harness
1. IG key "OFF"
2. Disconnect Instrument cluster connector and main fuel level sender connector.
3. Measure the resistance of both terminal of main fuel level sender harness.

Specification :Below 1Ohms




4. Is the resistance within specification?
