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.

  2.  

Testing



  1. Turn the ignition switch to the OFF position.
  2.  
  3. Disconnect the sensor electrical connector.
  4.  
  5. Using an ohmmeter measure the resistance between terminal 1 and 2 (component side).
  6.  
  7. Specification should be 2.21-2.69 ohms at 68 degrees F.
  8.  
  9. Replace the sensor, as required.
