I have a 2007 Fleetwood Providence. I am visiting my sister in Rhode Island and parked I her driveway. I have water and cable o sewer hookup. I have to empty the black tank every 7 to 9 days.

On one trip to the dealer to dump the tank, the secondary air gauge started going from zero to operating pressure and back and the warning buzzer starts. I paid for a mobile RV repairman and he could not find anything wrong. So I went to empty the black tank and it started going up and down after driving about 10 miles and was intermittent all the way back but still cannot here an air leak. Any suggestions?

fad847, Welcome to FMCA !

This is a thread the covers the problem with the gauges on most Freightliner Chassis.

You can read through the different posts on this thread, but it is most often caused by cold solder joints in the air module. The cost can vary, but you are looking at around $1000 when repaired at the service centers. So shop around!!!

Hi from Aggieland, Rich.

I know this is an older post but thought I would pass along this information.

I had the same low pressure nuisance alarm on my 2008 Freightliner chassis. I called the Freightliner help desk at 1-800-385-4357 and they sent me a new daisy chain wiring harness at no charge that attaches to the dash gauges.

I replaced the harness and I haven't had a problem since.

Gig'em Aggies,

Not sure this will help but on the Roadmaster Chassis we have that problem and the solution is to clean the road scum off of the top of the low pressure relay or sensor on top of the front tank the scum shorts out the wires causing a low air alarm.
