MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>

13A-553

STEP 10. Check for short circuit to ground between 
crankshaft position sensor intermediate connector B-119 
(terminal No. 2) and PCM connector B-22 (terminal No. 
103).

Q: Is the harness wire in good condition?

YES : Replace the PCM. Then go to Step 22.
NO :  Repair it. Then go to Step 22.

STEP 11. Measure the power supply voltage at crankshaft 
position sensor intermediate harness side connector 
B-119.

(1) Disconnect the connector B-119 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 13.
NO :  Go to Step 12.

STEP 12. Check harness connector B-17X at MFI relay for 
damage.

Q: Is the harness connector in good condition?

YES : Repair harness wire between MFI relay connector 

B-17X (terminal No. 4) and crankshaft position sensor 
intermediate connector B-119 (terminal No. 1) 
because of open circuit or short circuit to ground. 
Then go to Step 22.

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

Connector Inspection 

P.00E-2

. Then go to Step 22.

STEP 13. Check the continuity at crankshaft position 
sensor intermediate harness side connector B-119.

(1) Disconnect the connector B-119 and measure at the 

harness side.

(2) Check for the continuity between terminal No. 3 and 

ground.

• Should be less than 2 ohms.

Q: Does continuity exist?

YES : Go to Step 16.
NO :  Go to Step 14.

STEP 14. Check harness connector B-22 at PCM for 
damage.

Q: Is the harness connector in good condition?

YES : Go to Step 15.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. Then go to Step 22.

STEP 15. Check for open circuit and harness damage 
between crankshaft position sensor intermediate 
connector B-119 (terminal No. 3) and PCM connector B-22 
(terminal No. 113).

Q: Is the harness wire in good condition?

YES : Replace the PCM. Then go to Step 22.
NO :  Repair it. Then go to Step 22.

STEP 16. Check harness connector B-17X at the MFI relay 
for damage.

Q: Is the harness connector in good condition?

YES : Go to Step 17.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection
