David Kast Posted October 7, 2022 Share Posted October 7, 2022 08 Monaco Dynasty Renaissance Hey everyone, I have posted about this a couple times on other sites 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 Link to comment Share on other sites More sharing options...
vito.a Posted October 7, 2022 Share Posted October 7, 2022 Who manufactured your original throttle assembly? Was it Kongsberg? What engine is in your coach? The reason I ask is the throttle position sensor must communicate with the engine ECM. Do you still have the original throttle position sensor? If so, don't let it out of your sight! 1 Link to comment Share on other sites More sharing options...
David Kast Posted October 7, 2022 Author Share Posted October 7, 2022 Teleflex, but was eventually sold to several companies but is not sold, serviced and discontinued. That is the main problem with modern replacements the are not communicating with the systems. 1 Link to comment Share on other sites More sharing options...

Frank McElroy Posted October 7, 2022 Share Posted October 7, 2022 The schematic for the throttle position sensor is available through Cummins Quickserve. Here is a screenshot for your 08 dynasty with a CM2150 ISL. The Electronic Control Module OEM connection wiring is what Monaco installed following the Cummins schematic. The throttle position sensor is not plug and play. I assume that the sensors tried met the resistance requirements from Cummins for full throttle and no throttle positions and resistance through the rest of the throttle range. In addition each new TPS must be calibrated to the ECM before it will work. 1 1 Link to comment Share on other sites More sharing options...
Gary M Posted October 8, 2022 Share Posted October 8, 2022 I had to replace my Kongsburg sensor. Not sure if yours is the same. Bought mine off EBay. Even bought a spare. Link to comment Share on other sites More sharing options...

David Kast Posted March 4, 2023 Author Share Posted March 4, 2023 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. 08 Monaco Dynasty Renaissance Hey everyone, I have posted about this a couple times and still have not solved my problem.

Mike Fluharty Posted March 5, 2023 Share Posted March 5, 2023 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, 1 Link to comment Share on other sites More sharing options...

Gary M Posted March 6, 2023 Share Posted March 6, 2023 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. 1 Link to comment Share on other sites More sharing options...
BennieH Posted March 6, 2023 Share Posted March 6, 2023 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. 1 Link to comment Share on other sites More sharing options...

Constwkr Posted November 12, 2023 Share Posted November 12, 2023 I am looking for a TPS for my 07 Dynasty. I have talked to UltraRV products and they do not stock one for my 07 Dynasty. I have found the part # on my existing unit, 050G-E4634 but have not been able to locate any supplier for this unit. I saw on one post it is no longer made. If any one has any suggestions as to where I may locate one I would appreciate knowing. I did find one used one and that may be the way I will have to go.

Tom Cherry Posted November 12, 2023 Share Posted November 12, 2023 I just merged three topics, including the one just posted. If you do a Search for Throttle Position Sensor....there are TWO additional topics. It is requested, per the rules, that a search be done. Here is what I found... AGAIN from MEMORY. I THINK, but @Frank McElroy probably has more information or else has an email or updated the parts list, but there was, at least on the Cummins' engines, only ONE TPS. This was part, I recall of the total brake/accelerator system or the Adjustable pedals. Therefore, a NON-Adjustable or an Adjustable pedal assembly SHOULD have the SAME TPS. Here is some quick research.... Telefex model 67076-001 https://www.lumbermenonline.com/ManufacturedPDFs/35/RVInfo2.pdf https://www.irv2.com/forums/f115/09-knight-kongsberg-pedal-sensor-failure-436112.html https://www.irv2.com/forums/f115/08-camelot-throttle-position-sensor-problem-126061.html OKI...I have been down this path before. There is an expensive FIX that is in our files. Williams, who is still in business has a unit that will work. Not a OMG, but close job....depending on your skill set. It is in one of the posts. You can download the File. If you use the above link, I followed it, many years ago. I actually chased down the rep in the post. He said.....BASICALLY....there is NO REPLACEMENT PART out there. They discontinued and he was sort of like the "Last of the Mohicans" and he helped people out. There USED to be a lot of these on ebay. I could KICK myself for not buying one....but then they show up every once and a while. The unit was manufactured by Kongsberg. They had a recall of them....not for the TPS or the "sensor" assembly, but for a potential "mechanical" issue. Kongsberg, whom I worked with as an UNPAID consultant...as I felt sorry for the QC guy that had NEVER done a major Automotive recall came up with a bracket. You installed it. MANY did, but probably only 20% or so were ever "modified". The failure that most have....is NOT PART OF THE MECHANICAL ISSUES.....just...."I ain't working no more". You can do a WHOLE lot of GOOGLING use the Model number (67076-001). Teleflex, MEMORY...and VERY SKETCHY....USED to have a "rheostat" for lack of a better name or the actual "rotating part" that would interchange....and you had to do some wiring mods....but it worked. That's about it for my brain....other than this pops up from time to time....and probably, as our rigs age out....more and MORE. 1 Link to comment Share on other sites More sharing options...
