MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <2.4L>

13A-713

STEP 6. Check connector B-14 at the barometric pressure 
sensor and connector C-60 at ECM <M/T> or connector 
C-54 at PCM <A/T> for damage.
Q: Is the connector in good condition?

YES : Repair harness wire between barometric pressure 

sensor connector B-14 (terminal No. 2) and ECM 
connector C-60 (terminal No. 85) <M/T> or PCM 
connector C-54 (terminal No. 55) <A/T> because of 
open circuit or harness damage. Then go to Step 18.

NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. Then go to Step 18.

STEP 7. Measure the sensor supply voltage at barometric 
pressure sensor connector B-14 by backprobing.
(1) Do not disconnect the connector B-14.
(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between terminal No. 1 and ground by 

backprobing.

• Voltage should be between 4.8 and 5.2 volts.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage between 4.8 and 5.2 volts?

YES : Go to Step 12.
NO :  Go to Step 8.
