    I've started have problems with the Low Air Alarm sounding from time to time, yet the air pressure is 120 lbs. in both primary & secondary circuits.

    A quick look under the dash reveled 4 sensors. Any idea which might be the one for the reserve tank...?

    I found the sensor on the right side of the brake pedal and removing one of the two wires silenced the alarm. I'm hoping I can take the sensor off and 'Unstick' it, but the local dealer doesn't have a replacement in stock, so I'll wait until I get home and have the parts in hand before I tear it apart. Thanks for the assistance...!
