Verification of Vehicle Repair
After a repair, it is essential to verify that the fault has been corrected.
1. Connect GDS and select "DTC" button.
2. Press "DTC Status" button and confirm that "DTC Readiness Flag" indicates "Completed". If not, drive the vehicle
within conditions noted in the freeze frame data or enable conditions.
3. Read "DTC Status" parameter.
4. Is parameter displayed "History(Not Present) fault" ?
▶ System performing to specification at this time. Clear the DTC.
▶ Go to the applicable troubleshooting procedure.

Component Location

General Description
The Intake Air Temperature Sensor (IATS) is installed into the Mass Air Flow Sensor (MAFS). The IATS uses a
thermistor whose resistance changes with the temperature. The electrical resistance of the IATS decreases as the
temperature increases, and increases as the temperature decreases. The 5 V power source in the ECM is supplied to
the IATS via a resistor in the ECM. That is, the resistor in the ECM and the thermistor in the IATS are connected in
series. When the resistance value of the thermistor in IATS changes according to the intake air temperature, the signal
voltage also changes. Using this signal, the information of the intake air temperature, the ECM corrects basic fuel
injection duration and ignition timing
DTC Description
ECM monitors temperature difference betwen MAX. and MIN IATS in order to detect movement in IATS not only Start
Test but Drive Test while enable condition is met. If ECM detects intake air temperature changes less than 5.4 °F ECM
determines that a fault exists and a DTC is stored.
MIL(Malfunction Indication Lamp) turns on when the malfunction lasts till consecutive 2 driving cycle.
