STEP 1. Using scan tool MB991958, check data list item 5:
Intake Air Temperature Sensor.

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) 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.
(3) Measure the resistance between intake air temperature

sensor side connector terminal No. 1 and No. 4.

(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.

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 22

P.13B-11

.

(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, Diagnosis
− ID Codes Registration Judgment Table <Vehicles

with KOS>

P.42B-15

or GROUP 42C, Diagnosis

− ID
