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 terminal 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 8.

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 

Connector Inspection 

P.00E-2

. Then go to Step 8.

STEP 4. Check the continuity at PCM harness side 
connector D-136.
(1) Disconnect the connector D-136 and measure at the 

harness side.

(2) Measure the continuity between terminals No. 144, No. 145 

and ground.

• Should be less than 2 ohms.

Q: Is the continuity normal? 

YES : Go to Step 5.
NO :  Check harness connector D-14 at ground joint 

connector for damage, and repair or replace as 
required. Refer to GROUP 00E, Harness Connector 
Inspection 

P.00E-2

. If ground joint connector D-14 is 

in good condition, repair it because of open circuit or 
harness damage between PCM connector D-136 
(terminals No. 144, No. 145) and ground. Then go to 
Step 8.

STEP 5. Check for open circuit and harness damage 
between throttle actuator control motor connector B-05 
(terminal No. 6) and PCM connector D-136 (terminal No. 
133).
Q: Is the harness wire in good condition?

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

STEP 6. Check for open circuit and harness damage 
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 7.
NO :  Repair it. Then go to Step 8.

STEP 7. 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 P2100 set?

YES : Replace the PCM. Then go to Step 8.
NO :  It can be assumed that this malfunction is intermittent. 

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