MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS TSB Revision MULTIPORT FUEL INJECTION (MFI) <3.8L ENGINE> 13B-977 STEP 8. Check the left bank injector. (1) Disconnect the left bank injector connector B-27, B-26, B-30. (2) Measure the resistance between each injector side connector terminal No. 1 and No. 2. Standard value: 10.5 − 13.5 ohms [at 20°C (68°F)] Q: Is the measured resistance between 10.5 and 13.5 ohms [at 20 °C (68°F)]? YES : Go to Step 9. malfunction symptom is eliminated. STEP 9. Check the right bank injector resistance at (1) Disconnect the intermediate connector B-32. (2) Measure the resistance between each male connector side terminal. a. Measure the resistance between terminal No. 5 and No. 9 at No. 1 cylinder injector. b. Measure the resistance between terminal No. 9 and No. 10 at No. 3 cylinder injector. c. Measure the resistance between terminal No. 4 and No. 9 at No. 5 cylinder injector. • Resistance should be between 10.5 and 13.5 ohms [at 20 °C (68°F)]. Q: Is the measured resistance between 10.5 and 13.5 ohms [at 20 °C (68°F)]? YES : Go to Step 12.
