Intake Air Temperature (IAT) Sensor

Print

Operation



This sensor is a resistor based sensor which detects the intake air temperature. According to the intake air temperature reading the ECM/PCM will control the necessary amount of fuel injection.

Removal & Installation



  1. Disconnect the negative battery cable.
  2.  
  3. Disconnect the connector from the sensor.
  4.  
  5. Remove the sensor retaining screws, as required.
  6.  
  7. Remove the air cleaner and air intake assembly, as required.
  8.  
  9. Remove the sensor from its mounting.
  10.  

To install:

  1. Installation is the reverse of the removal procedure.
  2.  

Testing



  1. Be sure the ignition is OFF.
  2.  
  3. Remove the sensor connector.
  4.  
  5. Using an ohmmeter measure the resistance between terminal 5 and 3 (component side).
  6.  
  7. On 2004 vehicles specification should be as follows:

    Intake air temperature -40 degrees, resistance 33.85-61.20 kohms
     
    Intake air temperature 68 degrees, resistance 2.33-2.97 kohms
     
    Intake air temperature 176 degrees, resistance 0.31-0.43 kohms
     

  8.  
  9. On 2005-2006 vehicles specification should be as follows:

    Intake air temperature -40 degrees, resistance 45.3 kohms
     
    Intake air temperature 68 degrees, resistance 2.50 kohms
     
    Intake air temperature 176 degrees, resistance 0.33 kohms
     

  10.  
  11. Replace the sensor, as required.
