W/Harness Inspection

P2067 Fuel Level Sensor \'B\' Circuit Low

Inspection/Repair - W/Harness Inspection

Terminal and Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness 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

Check voltage
1. IG "OFF" and disconnect Fuel Sender B connector.
2. IG "ON".
3. Measure voltage between total signal terminal of Fuel Sub Sender harness connector and chassis ground.

Specification : Approx. 11 - 12 V




4. Is the measured voltage within specification?





Check shorted in harness
1. IG "OFF" and disconnect Fuel Sender A & Fuel Pump Motor connector, Fuel Sub Sender B connector and PCM connector.
2. Measure resistance between middle signal terminal of PCM harness connector and chassis ground.

Specification : Infinite




3. Is the measured resistance within specification?





Check open in harness
1. IG "OFF" and disconnect Fuel Sender A & Fuel Pump Motor connector and PCM connector.
2. Measure resistance between total signal terminal of Fuel Sender and middle signal terminal of PCM harness connector.

Specification : Below 1 Ohms




3. Is the measured resistance within specification?
