MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS
TSB Revision
MULTIPORT FUEL INJECTION (MFI) <3.8L ENGINE>
13B-497
STEP 5. Check the No. 3 cylinder injector.
(1) Disconnect the No. 3 cylinder injector connector B-03.
(2) Measure the resistance between injector side connector
terminal No. 1 and No. 2.
Standard value: 10.5
− 13.5 ohms [at 20°C (68°F)]
Q: Is the resistance between 10.5 and 13.5 ohms [at 20
°C
(68
°F)]?
YES : Repair harness wire between intermediate connector
B-32 (terminal No. 9) and injector connector B-03
(terminal No. 1) and harness wire between No.3
cylinder injector connector B-03 (terminal No. 2)
and intermediate connector B-32 (terminal No. 10)
because of open circuit or short circuit to ground
or harness damage.
Then go to Step 12.
NO : Replace the No.3 cylinder injector. Then go to Step
12.
STEP 6. Measure the power supply voltage at intermediate
connector B-32.
(1) Disconnect the connector B-32 and measure at the female
connector side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal No. 9 and ground.
• Voltage should be battery positive voltage.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is battery positive voltage (approximately 12 volts)
present?
YES : Go to Step 8.
NO : Go to Step 7.
