STEP 2. Check the throttle actuator control motor.
(1) Disconnect the connector B-05.

(2) Measure the resistance between throttle actuator control

motor side connector terminals No. 5 and No. 6.

Standard value: 0.3

− 100 ohms

Q: Is the measured resistance between 0.3 and 100 ohms?

YES : Go to Step 3.
NO : Replace the throttle body ASSY. Then go to Step 7.

STEP 3. Check connector D-136 at PCM for damage.
Q: Is the connector in good condition?

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

STEP 5. Check for short circuit to ground between throttle
actuator control motor connector B-05 (terminal No. 5) and
PCM connector D-136 (terminal No. 141).
Q: Is the harness wire in good condition?

YES : Go to Step 6.
NO : Repair it. Then go to Step 7.

STEP 6. Using scan tool MB991502, read the diagnostic
trouble code (DTC).

CAUTION

To prevent damage to scan tool MB991502, always turn the
ignition switch to the "LOCK"(OFF) position before con-
necting or disconnecting scan tool MB991502.
(1) Connect scan tool MB991502 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 P2103 set?

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