MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS TSB Revision MULTIPORT FUEL INJECTION (MFI) 13A-307 STEP 7. Check the left bank injector resistance at (1) Disconnect the injector intermediate connector B-44. (2) Measure the resistance between each injector side connector terminal. a. Measure the resistance between terminal No. 2 and No. 8 at No. 2 cylinder. b. Measure the resistance between terminal No. 7 and No. 8 at No. 4 cylinder. c. Measure the resistance between terminal No. 5 and No. 8 at No. 6 cylinder. • Resistance should be between 13 and 16 ohms [at 20°C (68 °F)]. Q: Is the measured resistance between 13 and 16 ohms [at 20 °C (68°F)]? YES : Go to Step 10. STEP 8. Check connector B-33, B-35, B-11 at left bank (1) Remove the intake manifold. the standard value at Step 7. Q: Is the connector in good condition? YES : Go to Step 9. Connector Inspection . Then go to Step 14.
