MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>

13B-397

STEP 4. Check for open circuit and harness damage and 
short circuit to ground between the throttle position 
sensor connector B-08 and the ECM connector B-10.
(1) Disconnect the throttle position sensor connector B-08 and 

the ECM connector B-10.

(2) Measure the resistance between the throttle position sensor 

connector B-08 (terminal No. 5) and the ECM connector 
B-10 (terminal No. 12).

• Should be less than 2 ohms.

(3) Check for the continuity between the throttle position sensor 

connector B-08 (terminal No. 5) and ground.

• Not continuity.

Q: Is the harness wire in good condition?

YES : Replace the ECM. When the ECM is replaced, 

register the ID code. Refer to GROUP 42B, Diagnosis 
− ID Codes Registration Judgment Table <Vehicles 

with KOS> 

P.42B-15

 or GROUP 42C, Diagnosis 

− ID 

Codes Registration Judgment Table <Vehicles with 
WCM> 

P.42C-10

. Then go to step 8.

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

Inspection 

P.00E-2

. Then go to Step 8.

STEP 5. Check for open circuit and short circuit to ground 
and harness damage between the throttle position sensor 
connector B-08 and ECM connector B-10.
(1) Disconnect the throttle position sensor connector B-08 and 

the ECM connector B-10.

(2) Measure the resistance between the throttle position sensor 

connector B-08 (terminal No. 6) and the ECM connector 
B-10 (terminal No. 11).

• Should be less than 2 ohms.

(3) Check for the throttle position sensor connector B-08 

(terminal No. 6) and ground.

• Not continuity.

Q: Is the harness wire in good condition?

YES : Go to Step 6.
NO :  Repair it. Then go to Step 8.

MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>

13B-399

STEP 6. Using scan tool MB991958, check data list item 15: 
Throttle Position Sensor (sub).

CAUTION

To prevent damage to scan tool MB991958, always turn the 
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958 to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) Detach the intake air hose at the throttle body.
(4) Disconnect the connector of the throttle position sensor.
(5) Use test harness special tool (MB991658) to connect only 

terminals No. 3, No. 4, No. 5, and No. 6.

(6) Set scan tool MB991958 to the data reading mode for item 

15, Throttle Position Sensor (sub).

• Output voltage should be 4.0 volts or more when the 

throttle valve is fully closed with your finger.

• Output voltage should be 1.0 volt or less when the throt-

tle valve is fully open with your finger.

(7) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the sensor operating properly?

YES : It can be assumed that this malfunction is intermittent. 

Refer to GROUP 00, How to Use 
Troubleshooting/Inspection Service Points 

− How to 

Cope with Intermittent Malfunctions 

P.00-15

.

NO :  Go to Step 7.

STEP 7. Replace the throttle body assembly.
(1) Replace the throttle body assembly.
(2) Turn the ignition switch to the "ON" position.
(3) After the DTC has been deleted, read the DTC again.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC P0222 set?

YES : Replace the ECM. When the ECM is replaced, 

register the ID code. Refer to GROUP 42B, Diagnosis 
− ID Codes Registration Judgment Table <Vehicles 

with KOS> 

P.42B-15

 or GROUP 42C, Diagnosis 

− ID 

Codes Registration Judgment Table <Vehicles with 
WCM> 

P.42C-10

. Then go to Step 8.

NO :  The inspection is complete.

STEP 8. Using scan tool MB991958, read the diagnostic 
trouble code (DTC).

CAUTION

To prevent damage to scan tool MB991958, always turn the 
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958 to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) After the DTC has been deleted, read the DTC again.
