Humidity Sensor Test

NOTE: Before testing the sensor, check for climate control DTCs (see HOW TO USE THE SELF-DIAGNOSTIC FUNCTION WITH THE HDS ).
  1. Remove the humidity/in-car temperature sensor (see HUMIDITY/IN-CAR TEMPERATURE SENSOR REPLACEMENT ).
  2. Connect the humidity/in-car temperature sensor 4P connector.
  3. Turn the ignition switch to ON (II). Measure the voltage between terminals with the (+) probe on terminal No. 3 and the (-) probe on terminal No. 2 with the connector connected.
