MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>

13A-853

STEP 2. Check the throttle actuator control motor.

(1) Disconnect the connector B-06.

(2) Measure the resistance between throttle actuator control

motor side connector terminals 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

7.

STEP 3. Check harness connector B-23 at PCM 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 7.

STEP 4. Check for short circuit to ground between throttle
actuator control motor connector B-06 (terminal No. 1) and
PCM connector B-23 (terminal No. 147).

Q: Is the harness wire in good condition?

YES : Go to Step 5.
NO : Repair it. Then go to Step 7.

STEP 6. 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.
(4) Turn the ignition switch to the "LOCK"(OFF) position.
Q: Is DTC P2102 set?

YES : Replace the PCM. Then go to Step 7.
NO : It can be assumed that this malfunction is intermittent.

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

P.00-6
