MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS TSB Revision MULTIPORT FUEL INJECTION (MFI) 13A-123 STEP 11. Check the engine coolant temperature sensor. connector B-37. (2) Remove the engine coolant temperature sensor. (3) With the temperature sensing portion of engine coolant temperature sensor immersed in hot water, check Standard value: 14 − 17 kΩ [at −20°C (−4°F)] 5.1 − 6.5 kΩ [at 0°C (32°F)] 2.1 − 2.7 kΩ [at 20°C (68°F)] 0.9 − 1.3 kΩ [at 40°C (104°F)] 0.48 − 0.68kΩ [at 60°C (140°F)] 0.26 − 0.36 kΩ [at 80°C (176°F)] (4) Apply 3M AAD part number 8731 or equivalent on the screw section of the engine coolant temperature sensor. (5) Install the engine coolant temperature sensor, and tighten to the specified torque. Tightening torque: 29 ± 10 N⋅m (22 ± 7 ft-lb) Q: Is the resistance at the standard value? YES : Go to Step 12. go to Step 14. STEP 12. Check connector D-135 at PCM for damage. YES : Go to Step 13. Connector Inspection . Then go to Step 14.
