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 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 24 P.
13Ab-8.
(2)
Check the diagnostic trouble code (DTC).
Q:Is DTC P0112 set?
YES:
Replace the ECM. When the ECM is replaced, register
the ID code. Refer to GROUP 42B, ID Code Registration

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.

DIAGNOSTIC TROUBLE CODE PROCEDURES
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.
⦆
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.

continued to be 4.6 volts or higher [corresponding
to an air intake temperature of -40°C (-40°F) or
lower] for 2 seconds.
OBD-II DRIVE CYCLE PATTERN
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.
