Throttle position sensor fix


Recommended Posts

Updated March/4/2023

We picked Up the coach this past Thursday and all is working well. Our total repair bill for all parts,labor and R&D was $6400.00. Now that it's done and we developed the repair it should cost aprox. $3000.00. We will be sharing the repair method free for all as karma. I intend to call all the shops we called around the country and told us it could not be done including REV Group. Not sure how to share the repair on this forum but if you or someone you know has,had this problem reach out to me and I can email it to you with pat numbers. 

Thanks

David 

 

 

Update; February 25 2023

After months of research and 4 months in two different shops and the help from 5 major companies we believe we are the first one in the country to have a fix. We called every shop we could find or referred to even REV and their electronic companies they use to no avail. We were told by everyone the problem as stated below had no known repair. Electrical Engineers at Cummins, Allison,  Williams controls,  Pete's Diesel and Smith Power Products all helped in a first ever permanent fix. 

I will post an update when we pick it up next week as well as the total repair for this. As I stated above everyone around the country told us it would be a paper weight and no fix was possible. NOT ANYMORE.  Yeah us.

Hey everyone,  I have posted about this a couple times and still have not solved my problem. My TPS (throttle position sensor) went bad and we have to replace the intire assembly. I have found and downloaded the electrical schematics 279 pages which is great to have but it does not include the Accelerator petal circuit. I have called REV they gave me the part number and original manufacturer but that company sold it to a few more companies and is no longer available and supported. The shop that's its in has tried a few newer Accelerator petal assemblies with the same plugs but they aren't working correctly and throw codes as shown on the first picture. I have called as well as the shop that has the coach so many companies and all dead ends.  Please help I can't be the only one that has,had this problem.  I have tried IRV2, searched this page as well as Bill D Monacoers.org  and nothing new to help. All advice is very much appreciated.

David, sounds like a home run.  I do not know your engine configuration so I don’t know if your fix should b something I should keep in my back pocket. I have a safari with an ISL 370, if you have an ISL XXX I would be interested in your parts list. The moderators may add it to the parts lists or technical bulletins that are available for download.

Thanks,

I’m also curious as my Throttle Positioning Sensor died back in 2018. But got lucky that Tom Cherry found the pedal and sensor on eBay. They were new with slight damage at connections but ordered, removed old, replaced and plugged in new one and drove back home to Oregon from Ohio.

David,

Congratulations! I've seen and read a number of threads on this issue and as a retired electronics engineer had often felt that it could be solved. I'll watch for the solution to be posted as I think it will be great reading!

Again, congratulations.

Would it be possible to add a picture or drawing of the bracket you had to make to adapt the foot feed?

Thanks for the info.

Mike

Great idea,  I will get ahold of the shop that did the fabrication for a drawing and add to the file.

Thanks for your feedback
