MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI)

13A-819

STEP 12. Measure the ground voltage at barometric 
pressure sensor connector B-48 by backprobing.
(1) Do not disconnect the connector B-48.
(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between terminal No. 5 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 voltage normal?

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

STEP 13. Check connector B-48 at the barometric pressure 
sensor and connector D-134 at PCM for damage.
Q: Is the connector in good condition?

YES : Go to Step 14.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. Then go to Step 18.
