CIRCUIT OPERATION
⦆
Approximately 5 volts are applied to the intake air
temperature sensor output terminal (terminal No. 1)
from the ECM (terminal No. 89) via the resistor in
the ECM. The ground terminal (terminal No. 4) is
grounded with ECM (terminal No. 88).
⦆
The intake air temperature sensor is a negative
temperature coefficient type of resistor. When the
intake air temperature rises, the resistance
decreases.
MULTIPORT INJECTION SYSTEM (MFI) <DIAGNOSIS>
13Ab-143
DIAGNOSTIC TROUBLE CODE PROCEDURES
⦆
The intake air temperature sensor output voltage
increases when the resistance increases and
decreases when the resistance decreases.
TECHNICAL DESCRIPTION
⦆
The intake air temperature sensor converts the
intake air temperature to a voltage.
⦆
The ECM checks whether this voltage is within a
specified range.
DESCRIPTIONS OF MONITOR METHODS
Intake air temperature sensor output voltage does
not change when specified go/stop operations are
repeated.

DIAGNOSTIC TROUBLE CODE PROCEDURES
⦆
Repeat 2 or more times: drive*1, stop*1.
⦆
Drive*1: vehicle speed higher than 50 km/h (31
mph) lasting a total of more than 60 seconds.
⦆
Stop*2: vehicle speed lower than 1.5 km/h (1.0
mph) lasting more than 30 seconds.
Judgement Criterion
⦆
Changes in the intake air temperature is lower than
1°C (1.8°F).
OBD-II DRIVE CYCLE PATTERN
Refer to Diagnostic Function - OBD-II Drive Cycle -
Pattern 8 P.13Ab-8.
TROUBLESHOOTING HINTS (The most likely
causes for this code to be set are: )
⦆
Intake air temperature sensor failed.
⦆
ECM failed.
DIAGNOSIS
Required Special Tools:
⦆
MB991958: Scan Tool (M.U.T.-III Sub Assembly)
⦆
MB991824: V.C.I.
⦆
MB991827: USB Cable
⦆
MB991910: Main Harness A
STEP 1. Using scan tool MB991958, check data list item 5:
Intake Air Temperature Sensor.

Data link
connector
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)
Remove the mass airflow sensor from the air intake hose.
(3)
Turn the ignition switch to the "ON" position.
(4)
Set scan tool MB991958 to the data reading mode for item
5, Intake Air Temperature Sensor.
(5)
Heating the sensor using a hair drier.
⦆
The indicated temperature increases.
NOTE:
Do not allow it to increase over 80°C (176°F).
(6)
Turn the ignition switch to the "LOCK" (OFF) position.
(7)
Attach the mass airflow sensor.
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 the intake air temperature sensor.
(1)
Disconnect the intake air temperature sensor connector
A-07.
(2)
Remove the mass airflow sensor.
