MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <2.4L>

13A-81

STEP 9. Check connector B-04 at the manifold absolute 
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 manifold absolute 

pressure sensor connector B-04 (terminal No. 3) and 
ECM connector C-60 (terminal No. 81) <M/T> or PCM 
connector C-54 (terminal No. 46) <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 12. Measure the ground voltage at manifold absolute 
pressure sensor connector B-04 by backprobing.
(1) Do not disconnect the connector B-04.
(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between terminal No. 2 and ground by 

backprobing.

• Voltage should be 0.5 volt or less.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage 0.5 volt or less?

YES : Go to Step 15.
NO :  Go to Step 13.
