Freightliner Air Bag issue

I have a 2004 Mandalay with a Freightliner chassis.

I fired it up today and the gauge for the front bags showed 120 PSI, all good.

The back bag gauge went to 150 psi and stayed there.

I cycled the bags and no change.

But the height of the rear is good, and the pop off valve is working.

I hear the air release when it fills.

I think I have a bad gauge.

What do you guys think ?

    Unfortunately I am on the road, and scheduled to leave on Monday.

    Call 1-800-385-4357 with the last 6 of your VIN and they will help you. I had a problem with mine last week and he gave the part numbers, instructions and where to purchase.

    That is the number to Freightliner.
