Component Inspection

Ignition "OFF".
Disconnect Fuel Tank Unit connector.
Measure resistance between terminal 1 and 2 of the Fuel Temperature Sensor connector (To Component Side).
1. Specification:
  At 0°C (32°F), Resistance 4~7 kΩ
  
  At 20°C (68°F), Resistance 2~3 kΩ
  
  At 40°C (104°F), Resistance 0.9~1.3 kΩ
  
  At 80°C (176°F), Resistance 0.2~0.4 kΩ

Is the measured resistance of FTS within specifications?
YES
- Substitute with a known - good PCM and check for proper operation.
  If the problem is corrected, replace PCM and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO
- Substitute with a known - good FTS and check for proper operation.
  If the problem is corrected, replace FTS and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
