To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before
connecting 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)

Set scan tool MB991958 to the data reading mode for item
5, Intake Air Temperature Sensor.

｠

The intake air temperature and temperature shown with the
scan tool should approximately match.

(4)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is the sensor operating properly?

YES:

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.

NO:

Go to Step 2.

STEP 2. Check harness connector A-07 at the intake air
temperature sensor and harness connector B-11 at the ECM
for damage.

Q:Is the harness connector in good condition?

YES:

Go to Step 3.

NO:

Repair it. Refer to GROUP 00E, Harness Connector

Inspection P.00E-2. Then go to Step 5.

STEP 3. Check the intake air temperature sensor.

(1)

Disconnect the intake air temperature sensor connector
A-07.

(2)

Remove the mass airflow sensor.

(4)

Measure resistance while heating the sensor using a hair
drier.

Standard value:

13 - 17 kΩ [at -20°C (-4°F)]
5.3 - 6.7 kΩ [at 0°C (32°F)]
2.3 - 3.0 kΩ [at 20°C (68°F)]
1.0 - 1.5 kΩ [at 40°C (104°F)]
0.56 - 0.76 kΩ [at 60°C (140°F)]
0.30 - 0.45 kΩ [at 80°C (176°F)]

Q:Is the measured resistance at the standard value?

YES:

Replace the mass airflow sensor. Then go to Step 5.

NO:

Go to Step 4.

STEP 4. Check for harness between the intake air
temperature sensor connector A-07 and the ECM connector
B-11.

(1)

Disconnect the intake air temperature sensor connector A-07
and the ECM connector B-11.

(2)

Measure the resistance between the intake air temperature
sensor connector A-07 (terminal No. 1) and the ECM
connector B-11 (terminal No. 89).

｠

Should be less than 2 ohms.

Q:Is the harness wire in good condition?

YES:

Go to Step 5.

NO:

Repair it. Then go to Step 5.

DIAGNOSTIC TROUBLE CODE PROCEDURES

STEP 5. 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 24 P.
13Ab-8.

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P0113 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.

NO:

It can be assumed that this malfunction is

intermittent. Refer to GROUP 00, How to Use
