Signal Circuit Inspection

1. IG "OFF" and disconnect Fuel Sender & Fuel Pump Motor connector.
2. IG "ON" & ENG "OFF"
3. Measure voltage between terminal 4 of Fuel Sender & Fuel Pump Motor harness connector and chassis ground.

   Specification: Approx. 12V

4. Is the measured voltage within specification?

YES 

• Go to " 2Check short to ground in harness" procedure.

NO 

• Repair open in harness and go to "VERIFICATION OF VEHICLE REPAIR " procedure.

1. IG "OFF" and disconnect Fuel sender & Fuel pump motor connector and PCM connector.
2. Measure resistance between terminal 6 of Fuel sender & Fuel pump motor harness connector and chassis ground.

   Specification: Infinite

3. Is the measured voltage within specification?

YES 

• Go to " 3Check open in harness" as follows.

NO 

• Repair short to ground in harness, and go to "VERIFICATION OF VEHICLE REPAIR " procedure.

1. IG "OFF" and disconnect Fuel sender & Fuel pump motor connector and PCM connector.
2. Measure resistance between terminal 6 of Fuel sender & Fuel pump motor connector and terminal 30 of PCM harness connector.

   Specification: Below 1Ω

3. Is the measured voltage within specification?

   YES 

   • Go to "COMPONENT INSPECTION " procedure.
