MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>

13A-625

.

CIRCUIT OPERATION

• Controls the current that is applied from the ECM 

(terminals No. 15, No. 16) to the throttle actuator 
control motor (terminals No. 1, No. 2).

.

TECHNICAL DESCRIPTION

• ECM varies the direction and the amperage of 

the current that is applied to the throttle actuator 
control motor in order to control the opening of 
the throttle valve.

.

DESCRIPTIONS OF MONITOR METHODS

The voltage difference between the throttle position 
sensor output voltage and the throttle position sensor 
output at the throttle actuator control motor relay off 
is smaller than the specified value.

.

MONITOR EXECUTION

Continuous

.

MONITOR EXECUTION CONDITIONS 
(Other monitor and Sensor)

Other Monitor (There is no temporary DTC stored 

in memory for the item monitored below)

• Not applicable

Sensor (The sensor below is determined to be 

normal)

• Not applicable

.

DTC SET CONDITIONS

Check Conditions

• Battery positive voltage is higher than 8.3 volts.

• The output voltage of the throttle position sensor 

(main) minus the proposed output voltage 
becomes 0.1 volt or more.

• The output voltage of the throttle position sensor 

(sub) minus the proposed output voltage 
becomes 0.1 volt or more.

• The drive duty of the throttle actuator control 

motor is 100 percent or more.

or

• Battery positive voltage is higher than 8.3 volts.

• The proposed output voltage minus the output 

voltage of the throttle position sensor (main) 
becomes 0.1 volt or more.

• The proposed output voltage minus the output 

voltage of the throttle position sensor (sub) 
becomes 0.1 volt or more.

• The drive duty of the throttle actuator control 

motor is 100 percent or more.

Judgement Criterion

• The output voltage of the throttle position sensor 

(main) minus the learning value of the middle 
-opened degree becomes 0.2 volt or less for 0.4 
second.

or

• The output voltage of the throttle position sensor 

(sub) minus the learning value of the middle 
-opened degree becomes 0.2 volt or less for 0.4 
second.

.

OBD-II DRIVE CYCLE PATTERN

None.

.

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

• Throttle actuator control motor failed.

• Open throttle actuator control motor circuit, har-

ness damage, or connector damage.

• ECM failed.

MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>

13A-626

DIAGNOSIS

Required Special Tools:

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

• MB991824: V.C.I.

• MB991827: USB Cable

• MB991910: Main Harness A

STEP 1. Check harness connector B-08 at throttle actuator 
control motor for damage.
Q: Is the harness connector in good condition?

YES : Go to Step 2.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. Then go to Step 9.

STEP 2. Check the throttle actuator control motor.
(1) Disconnect the connector B-08.
(2) Measure the resistance between throttle actuator control 

motor side connector terminal No. 1 and No. 2.

Standard value: 0.3 

− 80 ohms [at 20°C (68°F)]

Q: Is the measured resistance between 0.3 and 80 ohms [at 

20

°C (68°F)]?

YES : Go to Step 3.
NO :  Replace the throttle body assembly. Then go to Step 

9.

STEP 3. Check harness connector B-11 at ECM for damage
Q: Is the harness connector in good condition?

YES : Go to Step 4.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. Then go to Step 9.
