Is the measured resistance within specification?
YES
- Substitute with a known-good ECM/PCM and check for proper operation. If the problem is corrected, replace ECM/PCM and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO
- Substitute with a known-good Fuel Level Sensor and check for proper operation. If the problem is corrected, replace Fuel Level Sensor and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
