IAT Sensor 1 Inspection

NOTE:  Since there is no direct method to test the component itself, troubleshooting is performed on the related components.

Test Procedure 

Unit output voltage inspection

• Preparation
• • -

    MAF sensor/IAT sensor 1 connector (4P): disconnected

• Procedure
• • Jump the MAF sensor/IAT sensor 1 connector (4P) terminals No. 2 and No. 4 with a jumper wire.
  • Turn the vehicle to the ON mode.
  • Confirm the HDS [IAT Sensor (1) Voltage].

• Normal Conditions
• • -

    HDS [IAT Sensor (1) Voltage] value is less than 4.92 V  .

Results 

• If it is normal, there is a problem with MAF sensor/IAT sensor 1.
• If it is abnormal, there is a problem with other related components.
