Okay, This Is Ridiculous!

No air pressure on one of the two dash gauges.  A ringing alarm and a red exclamation point on the instrument panel.  A called off mini “vacation” to Florida.  A return to the COE campground.  That about sums it up.


The next day I started the Journey up and everything worked properly.  No alarm, no red exclamation point on the instrument panel. Perfect reading on the gauge showing the correct air pressure.

Can’t be.  But it was.  So I decided to test it out several times during the day yesterday and again today, all with the same result.

Everything is working properly, the gauge reads the correct air pressure just like the one underneath it on the dash. 

What could have happened?  I theorize that maybe there was some moisture or ice in one of the air tanks that caused the sensor to malfunction and sound the alarm.  With a bit of warmer weather, the moisture may have dried up or the ice melted.  When I drained the tanks the other day when I was troubleshooting the problem, no moisture came out, but if there was some ice, that might have been the culprit.

Well, that’s what I think happened.  Or we could have had a visit from Murphy’s cousin:


I’m going to keep starting the engine every couple of days and even take the Journey for a test drive or two.  When we leave the COE for our summer travels mid April, the first thing we’re doing is head up to the Freightliner RV Service Center in Gaffney, SC for our annual service.  If that pesky air pressure gauge acts up, at least we’ll be headed in the right direction to get it fixed.

Thanks for visiting and feel free to leave a comment.



  1. Sounds like Murphy was teasing with you. Now you still can take that vacation in Florida.

  2. Well I believe in Divine intervention. You were not supposed to go to Florida at that time.

  3. I like Jim and Sandie's thought.... you weren't meant to go at that time I guess.

  4. That gremlin was playing tricks on you, to t your from Murphy.
    Better luck on your next trip.

  5. Don't think it was the Gremlins... they really don't like cold weather;o)) Your ice theory sounds very right. These rigs are really not meant to be in cold like that.

  6. Well I don't care who or what it was, I just hate that you had to cancel your trip. Any "experts" who might confirm your theory around? There are folks who have to drive in cold weather. Does the ice thing happen to them? Anyone at freightliner answer questions by phone like at Winnebago?

  7. I'm not sure about air brake systems but when it comes to air tools that would tell me they haven't had air line lubricant in quite some time. That would probably get rid of Murphy and his cousin on that account.
    Be Safe and Enjoy!

    It's about time.

  8. I'm one of those that believes everything happens for a reason. It just wasn't meant to be this time.

  10. Yup, Murphy or Gremlins, or God didn't want you to go for some reason:)

  11. Paul, had you been running very long before the alarm or was that right after a startup? I'm with you on the moisture being at the top of the list but I'm also wondering if perhaps the gauge inlet had something restricting flow to cause a false report until you drained (the whatever it was moved after pressure released).

    pun alert - Of course it could also be you were trying to take a Journey on an Excursion :)

    1. Very punny! Actually I had the engine running for a good half hour filling up my tires. Then a shut down for about an hour, finally an 18 mile drive to the fuel stop where I shut it down. After about 10 minutes of fueling, I restarted the engine and the alarms went off.

      Even after I drained the tanks, the alarm was still going off and no reading on the gauge. The other gauge read normal.

      The reason I suspect moisture/ice is the extreme cold temps over the last few days and I hadn't drained the tanks since last Sept when I last ran the engine. Condensation?

  12. Maybe the Gremlin just has something against Florida:)

  13. I had this happen on our 2000 Winnebago, on Freightliner Ch.
    and finally after many stops at the shop it was a faulty sensor.
    Of course it was an intermittent problem and just acted up like yours. A real PIA.
