Ok i have one sensor to test and i dont know how so i am asking for help again. Part #102480 Idle Speed Thermister or also known as Constant Idle Switch Thermister. This switch has 2 connection tabs on it. I hooked up a tester and ran it uneder hot and cold water and it didnt seem to do anything, i was checking to see if it made a contact under hot and cold water like the Lambda sensor does. Anyone please help me with this so i can enjoy the summer driving my car. I am not electrical smart, i am electricly challenged so i need easy instructions to test this sensor. Thanks Mark 6683
