MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>

13B-201

Check Condition

• Ignition switch is "ON" position.

Judgement Criterion

• Throttle position sensor (main) output voltage 

should be 0.2 volt or less for 0.3 second.

.

OBD-II DRIVE CYCLE PATTERN

None.

.

TROUBLESHOOTING HINTS (The most 
likely causes for this code to be set are:)

• Throttle position sensor failed.

• Connector damage

• Harness damage

• ECM failed.

DIAGNOSIS

Required Special Tools:

• MB991958: Scan Tool (M.U.T.-III Sub Assembly)

• MB991824: V.C.I.

• MB991827: USB Cable

• MB991910: Main Harness A

• MB991658: Test Harness

STEP 1. Using scan tool MB991958, check data list item 13: 
Throttle Position Sensor (main).

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 

13, Throttle Position Sensor (main).

• Output voltage should be between 0.3 and 0.7 volt when 

the throttle valve is fully closed with your finger.

• Output voltage should be between 4.0 volts or more 

when the throttle 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 2.

STEP 2. Check harness connector B-08 at the throttle 
position sensor and harness connector B-10 at the ECM 
for damage.
Q: Is the harness connector in good condition?

YES : Go to Step 3.
NO :  Repair it. Refer to GROUP 00E, Harness Connector 

Inspection 

P.00E-2

. Then go to Step 6.

STEP 3. Measure the sensor supply voltage at throttle 
position sensor harness side connector B-08.
(1) Disconnect the connector B-08 and measure at the harness 

side.

(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal No. 5 and ground.

• Voltage should be between 4.9 and 5.1 volts.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage between 4.9 and 5.1 volts?

YES : Go to Step 5.
NO :  Go to Step 4.

STEP 4. Check for open circuit to ground or harness 
damage 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

. 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 to ground or harness 
damage 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. 4) and the ECM connector 
B-10 (terminal No. 10).

• Should be less than 2 ohms.

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

connector B-08 (terminal No. 4) 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.
