    Exclamation Ride Level Sensor

    Morning Gents,
    Is there a way to check a ride level sensor to see if it's working right? I had the back end of my 98 sts come way up in the rear and would not come down until I unplugged the drivers rear sensor...
    Please HELP!
    At 140.00 a sensor I want to replace the bad one not all 4.
    Thanks,
    Guy

    Does yours have road sensing suspension? If so,it would have 2 height sensors in the rear instead of one.

    Yes it has 2 sensors in the back. I disabled the drivers side now the rear end does not pump up to max height. So with that I think I unplugged the bad sensor. Do you know how to check these to find out if the sensor is shot?

    I think you are looking at the wrong sensors. Get under the car. There is a lever attached from the switch to the body. Not sure which side. That is the control for the ELC. Sounds like you are pumping up the shocks but not releasing the air when needed. There is an exhaust valve on the ELC compressor. That may be your problem.

    Morning Ranger.
    There are 2 level sensors attached to the inside of the wheel well, then a rod that attaches to the "a" arm. What your saying makes sence. The reason I say that is because now with one of the level sensors(driver side) today again the car pumped up the back end and stayed there! Help me fix this thing. If I'm understanding this correctly there is a sensor that tells the compressor to exhaust? Thank you for your help so far as I have not ran out and bought a level sensor at 140.00 a pop at cost!
    Thank you.

    A service manual would be invaluable at this point. If you don't have one, do a search for ELC exhaust valve or something similar.
