MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <2.4L>

13A-169

STEP3. Check the throttle position sensor.
(1) Disconnect the connector B-07.

(2) Measure the resistance between throttle position sensor 

side connector terminal No. 1 and No. 4.

Standard value: 3.5 

 6.5 k

(3) Measure resistance between the throttle position sensor 

side connector terminal No. 1 and No. 3.

(4) Move the throttle valve from the idle position to the full-open 

position.

• Resistance should change smoothly in proportion to the 

opening angle of the throttle valve.

Q: Is the resistance normal?

YES : Go to Step 4.
NO :  Replace the throttle position sensor. Refer to 

P.13A-946

, Throttle Body. Then go to Step 14.

STEP 4. Measure the sensor supply voltage at throttle 
position sensor harness side connector B-07.
(1) Disconnect the connector B-07 and measure at the harness 

side.

(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between terminal No. 4 and ground.

• 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 7.
NO :  Go to Step 5.

STEP 5. Check 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 : . Go to Step 6.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection

STEP 6. Check for harness damage between throttle 
position sensor connector B-07 (terminal No. 3) and ECM 
connector C-60 (terminal No. 81) <M/T> or PCM connector 
C-54 (terminal No. 46) <A/T>.
Q: Is the harness wire in good condition?

YES : Replace the ECM or PCM. Then go to Step 14.
NO :  Repair it. Then go to Step 14.
