TSB Revision

MULTIPORT FUEL INJECTION (MFI)

13A-495

STEP 12. Check the continuity at camshaft position sensor 
intermediate connector B-08.
(1) Disconnect the connector B-08 and measure at the female 

side.

(2) Check for the continuity between terminal No. 1 and 

ground.

• Should be less than 2 ohms.

Q: Does continuity exist?

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

STEP 13. Check 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 21.

STEP 14. Check for open circuit and harness damage 
between camshaft position sensor intermediate connector 
B-08 (terminal No. 1) and PCM connector D-134 (terminal 
No. 88).
Q: Is the harness wire in good condition?

YES : Replace the PCM. Then go to Step 21.
NO :  Repair it. Then go to Step 21.

STEP 15. Check connector B-22X at the MFI relay for 
damage.
Q: Is the connector in good condition?

YES : Go to Step 16.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. Then go to Step 21.

. Then go to Step 21.

STEP 17. Check for open circuit or short circuit to ground 
or harness damage between MFI relay connector B-22X 
(terminal No. 1) and camshaft position sensor connector 
B-10 (terminal No. 3).

NOTE: Check harness after checking intermediate connector 
B-08. If intermediate connector B-08 is damaged, repair or 
replace it. Refer to GROUP 00E, Harness Connector Inspec-
tion
