MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS
TSB Revision
MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>
13A-465
STEP 3. Check the No. 1 cylinder injector.
(1) Disconnect the No. 1 cylinder injector connector B-01.
(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 measured resistance between 10.5 and 13.5 ohms
[at 20
°C (68°F)]?
YES : Go to Step 4.
NO : Replace the No. 1 cylinder injector. Then go to Step
10.
STEP 4. Measure the power supply voltage at No. 1
cylinder injector connector.
(1) Disconnect connector B-01 and measure at the harness
side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal No. 1 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 6.
NO : Go to Step 5.
