sprinter loses power

[benmj]

I have an Itasca Navion that loses power sometimes, especially in the mountains. Then it's back in the shop and they replace either the ambient or the internal temperature sensor. This happened twice on a recent trip. They can't seem to figure out why this happens. Sometimes the engine light comes on and we do not lose power. HELP! Our warranty expires in a week!!

Try posting on the View Navion group on yahoo.com groups. Many knowledgeable View Navion owners who are willing to assist.

You might consider copying this post to the Winnebago forum, you might find some folks there with similar issues.

Welcome to iRV2... If you have not been so welcomed. We have lost 2 turbos in our Cat C7 in 2 months... Add the year of your motor home to your signature. It might help get more responses. Regards .. D

I had a 2004 Navion that lost power due to a defective/cracked resonator. The resonator in that year was mounted under the engine and susceptible to being cracked by small stones and road debris thrown up by the tires, etc. It was made of a black plastic material that looks like black PVC. I took to carrying a spare. At that time it became a well known problem and easy to check by a mechanic aware of the issue. Hope that helps you out.

Winnebago didn't make the Navion and View until their 2006 model year. Early ones are on 2005 Sprinter chassis, then 2006 Sprinter chassis. The 2007 Views and Navions are on 2006 chassis. Those 5-cylinder diesel models had a device called a "turbo resonator" which was prone to splitting and rendering the vehicle in LHM (limp home mode). LHM caused by a defective turbo resonator is not temporary - it will have significantly reduced power until the resonator is replaced.

The later V-6 Sprinter diesels (on 2008 and later Views and Navions) don't suffer from the resonator problem, but can loose turbo pressure because of a turbo hose problem. I'm not that familiar with that issue.
