MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS TSB Revision MULTIPORT FUEL INJECTION (MFI) 13A-159 STEP 2. Measure the sensor output voltage at engine (3) Measure the voltage between terminal No. 1 and ground by backprobing. • When engine coolant temperature is −20°C (−4°F), volt- age should be between 3.9 and 4.5 volts. • When engine coolant temperature is 0°C (32°F), voltage should be between 3.2 and 3.8 volts. • When engine coolant temperature is 20°C (68°F), volt- age should be between 2.3 and 2.9 volts. • When engine coolant temperature is 40°C (104°F), volt- age should be between 1.3 and 1.9 volts. • When engine coolant temperature is 60°C (140°F), volt- age should be between 0.7 and 1.3 volts. • When engine coolant temperature is 80°C (176°F), volt- age should be between 0.3 and 0.9 volt. (4) Turn the ignition switch to the "LOCK" (OFF) position. YES : Go to Step 3. STEP 3. Check connector B-37 at the engine coolant YES : Go to Step 4. Connector Inspection . Then go to Step 14.
