DIAGNOSTIC TROUBLE CODE PROCEDURES

Q:Are they operating properly?

YES:

Go to Step 3.

NO:

Repair or replace it. Then go to Step 8.

STEP 3. Check harness connector B-08 at throttle actuator
control motor and harness connector B-10 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 8.

STEP 4. Check the throttle actuator control motor.

Throttle actuator
control motor
connector

(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 Ω [at 20°C (68°C)]

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

20°C (68°C)?

YES:

Go to Step 5.

NO:

Replace the throttle body assembly. Then go Step 8.

STEP 5. Check for harness damage between throttle
actuator control motor connector B-08 and ECM connector
B-10.

Connector B-08 (terminal No. 2) and connector B-10
(terminal No. 16).

｠

Should be less than 2 ohms.

Q:Is the measured resistance less than 2 ohms?

YES:

Then go to Step 6.

NO:

Repair it. Then go to Step 8.

STEP 6. Check for intake system vacuum leak.

Q:Are there any abnormalities?

YES:

Repair it. Then go to Step 8.

DIAGNOSTIC TROUBLE CODE PROCEDURES

NO:

Go to Step 7.

STEP 7. Check the trouble symptoms.

(1)

Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic Function - OBD-II Drive Cycle Pattern 17 P.
13Ab-8.

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P1241 set?

YES:

Replace the ECM. When the ECM is replaced, register

the ID code. Refer to GROUP 42B, ID Code Registration
Judgment Table <Vehicles with KOS> P.42B-12or GROUP
42C, ID Code Registration Judgment Table <Vehicles with
WCM> P.42C-8. 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 - How to Cope
with Intermittent Malfunctions P.00-15.

STEP 8. Test the OBD-II drive cycle.

(1)

Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic Function - OBD-II Drive Cycle Pattern 17 P.
13Ab-8.

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P1241 set?

YES:

Retry the troubleshooting.

NO:

The inspection is complete.
