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 3.

NO:

 Go to Step 3.

STEP 3. 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  8  P.
13Ab-8.

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P0111 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
Troubleshooting/Inspection Service Points How to Cope
with Intermittent Malfunctions P.00-15.

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>

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 is out
of specified range.

2 seconds or more have passed since the engine
starting sequence was completed.

Judgement Criterion

｠

Intake  air  temperature  sensor  output  voltage  has
continued to be 0.2 volt or lower [corresponding to
an  air  intake  temperature  of  115°C  (239°F)  or
higher] for 2 seconds.

Refer to Diagnostic Function - OBD-II Drive Cycle -
Pattern 24 P.13Ab-8.

TROUBLESHOOTING HINTS (The most likely
causes for this code to be set are:)

｠

Intake air temperature sensor failed.

｠

Connector damage

｠

Harness damage

｠

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)

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:

 t 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.
