Problems with Air Pressure guage going off randomly

[Rosie]

I have a problem with my air pressure. After I build up my air and start travelling, my air gauge will go down to zero on the gauge for 30 seconds or less then builds right back up. During this time the low air buzzer comes on but at no point do I lose air pressure. Has anyone had this problem. Its a 2002 Itasca.

May have a bad governor and/or check valve.

Air Brakes - low air pressure warning buzzer came on

There are a number of discussions on this site around a VDC control module that has a bad solder connection in it. Although I have not attempted this repair myself, there are many who have indicated that it solved the problem of momentary gauge inactivity that sets off the low air warning buzzer.

I hope this helps :-)
