Problems after insulating W-22 dog house

[RTZ6885]

I just recently insulated my W-22 doghouse in my 04 Winnebago Adventurer using Dynamat Hoodliner from Summit Racing. I just left on our vacation for out west when about an hour done the road the engine went into "reduced engine power mode" with check engine light so I coasted off to the shoulder. After an hour of checking battery, grounds etc, I restarted but the check engine light and reduced engine power message was still there. Then I opened the dog house and looked for anything obvious, checked any connectors I could find and closed the doghouse, restarted and everything was fine, I thought. So I started down the road and after about 10 minutes the check engine light came on as well as the reduced engine power message. So once again I managed to coast to an off ramp into a parking lot. This time on a hunch I removed the hoodliner insulation, restarted and again everything was normal. After a 1000 miles I haven't had that problem since. The hoodliner had never come loose but I did notice the close proximity to the engine when I looked through the passenger wheel well. My thinking is that the reflective shield was reflecting too much heat back over the engine and causing sensor failures.

......or possibly restricting air flow around the engine?

Our Sightseer just have the reflective shield without the insulation. Works well for us. Reduces the heat through the dog-house. Prior to the reflective shield being installed, we could feel the dog-house warm-up. Melted my chocolate candy I eat along the way while driving. Now, it's different. The heat is greatly reduced. Dealer installed the shield. They highly recommeded not going for the insulated shield because of the space restrictions and potential fire hazard.

Relax, drive safely, and enjoy God's creations.

I've never heard of any other vehicle going into 'reduced engine power ' or 'limp mode except for the Workhorse. I've also never heard of the WH going into limp mode for a good reason, like no oil pressure or even overheating. I believe WH's parameters, in their computer, send it into limpmode are way too liberal, just giving their customers grief. I don't understand why they don't just do away with it until they learn how to do it.
Mine did it once, reduced power and check engine light, turned it off, reduced power was gone , but check engine light stayed on for 1600 more miles but ran fine. I had to take it to a svc cntr to get the light turned off.
Even when I disconnected the battery, the light came back on when I reconnected . I thought that would erase it's memory.
WH gave us lots of little frills that just give us headaches.

We have the same hoodliner....No engine problems here....

THIS IS WHAT THIS STUFF IS MADE FOR! Hood lining. I find it hard to believe that somehow the reflective capabilities of this insulation somehow caused the engine to quit....

Should we not insulate our doghouses then? What about an inferior product that WONT reflect heat and sound?

We just got back from a 4,000 mile round trip from Colorado to Florida and back...no problems...

also just got back from record setting temps in Denver....no problems...

Depending on the coach (The body builder) some workhorse motor homes have a serious problem with air flow to start with, this results, usually, in fresh charred spark plug wires mis-fire and loss of power.

Though my rig does not seem to have that problem.. I would hesitate to do anything which reduced air flow around the engine.


My suggestion is to read the computer codes and see if you can find out what the problem is. You need a code scanner to do that

I have been using the Summit Hoodliner, apx. 1/2" thick, adhesive one side & reflective the other, for about 6,000 miles and have not had any problems. I did notice the close clearance when I installed it on the doghouse but it still left a little room. Sure does reduce noise and doghouse heat. You got me wondering as I have not driven in any 100 degree temps yet?

You continue to vent your misunderstanding about what limp mode is in the direction of the wrong manufacturer.

General Motors and Allison Transmission have written code that runs in both the ECM (yours a PCM) and the TCM (which you don't have).

Both GM and Allison provide the limp mode functionality for we Workhorse owners so that the automotive powertrain simply does not fail resulting in a stall and no power.

I would much rather have the "option" to crawl out of the way rather than get firmly stuck on the roadway and block traffic.

Limp mode isn't a conspiracy of the RV Industry trying to screw with motorhome owners.

GM/Allison isn't the only company that will make limp mode available to their customers. Ford and everybody else has it IF they have any type on computer controls in their automotive products.

I may be one of the fortunate ones in that to this date I have not had an overheat problem in my W-20 Winnebago Adventurer 33V. In fact on our most recent trip, coming home from Kansas City in 90 degree heat with the basement air on, I commented to my better half that the dog house was not even warm. I do have what seems to be ample room for air movement above and on both sides of the engine. My last coach was an Itasca Sunflyer on the Ford chassis and the dog house was always almost too hot to touch - and the floor under drivers feet was quite hot as well. We are planning a long trip to Glacier and Lake Louise in late August and September - hope I haven't just jinxed myself!!

Driver, I stand by my original statement!
I have NEVER heard of any other vehicle going into "Limp Mode" . Not once!
This includes any vehicle I have ever owned, Ford and GM products including a Blazer, 2 different GM powered boat engines. I also have never heard about it from any one that owns a vehicle and not on these forums either except Workhorse. I do not believe that WH has not messedwith these engines. I know GM certainly wants no part of Actia instrument clusters.
Speaking of which, I've never heard of any other vehicle that the odometer and instrument panel become illegible to read either.
Just admit it Driver, Workhorse has some screwed up vendors.

[max49]

Driver, I have not heard of these engines ever going into Limp mode for a good reason, like no oil pressure or severe overheating either. Every single time I have heard about it, somebody just turns it off and back on and it runs fine; until WH sends it back into limp mode again.
Now if someone has heard of limp mode saving them from a catastrphic failure, please let me know, but be honest.
Now why could'nt WH just spell out a message in their Actiathat says, "please stop now because there might something wrong with YOUR engine. Afterall, it is our engine, is'nt it?

I had the "reduced engine power" message four times during the first 1000 miles of operation. Final resolution was a loose fuse holder with no problems since. With my failures the "reduced engine power" or "limp mode" was a misnomer. The engine had a lot of trouble just trying to idle and the instant you put it in gear it would die. In my case the readout should have been "no engine power".

This can originate from any number of points however a code is retained in the non-volatile memory of the computer so a technician can diagnose what occurred. I experienced a REP and I got off the road, shut down the engine, waited for about a minute, restarted the engine and I was off like nothing happened. What was retained was the code in memory. Once back at the shop it was easy to diagnose the problem with a Tech II instrument.

The Ford Triton engine has a run hot mode. If you boil out the coolant out of a Triton engine it'll continue to run in a reduced power mode or until you can get off the road.

There are many more different types of system over rides that will occur in vehicles equipped with computers enabling them to get off the road in the event of an emergency.

I don't know of any vehicles when a system failure occurs where the driver would be given a choice as to whether or not the vehicle's computer will allow you the prerogative to continue to operate in the event of a failure.

As far as I know Workhorse and Actia have indeed resolved the IP issue with the release of the new 2007 IP. It's a good piece of equipment with increased functionality, visibility and more pleasing appearance. I want to say this again so there is no mistaking what will happen in the event of an IP failure, pixel drop out or any other issue related to the past generation of Actia IPs. Each failure will be handled on a case by case basis and to my knowledge there have been "0" denials of service by Workhorse or Actia regarding a problem IP. Technology improves daily and we are seeing this with the new Actia IP. To date I have not heard of any failures with the "07" improved IP. So it's getting better.

Any manufacturer or supplier that will continue to honor warranty claims and improve their product past the original new vehicle warranty is OK by me.
