Paul Busch Posted March 14, 2021 Share Posted March 14, 2021 I think I asked this before but got no response. Detroit series 60 14L. Going through West Virginia in November 2020 claiming the long hills my check engine light came on. Going down the hills it would go out and on again with the climbing. It finally stays on all the time. I changed fuel filters , hydraulic filter and all fluids are as should be. Any Ideas? Paul Link to comment Share on other sites More sharing options...
Gary M Posted March 14, 2021 Share Posted March 14, 2021 Well I wish I knew but my coach recently was doing the exact same thing. My issue was the turbo actuator. 07 EPA 360 Cummins. But after about a half hour the engine berated and could not go over 10 mph. Link to comment Share on other sites More sharing options...
Bob Wightman Posted March 14, 2021 Share Posted March 14, 2021 I had sorta the same problem on my last coach, which was a 1997 Ford F53 chassis gasser. The problem is that the transmission was getting hot, turned out the transmission was a little low on fluid, had the transmission serviced (fluid change & filter) and it fixed the problem. Don't know if thats whats going on for you but it's somewhere to look. Link to comment Share on other sites More sharing options...
Paul Busch Posted March 14, 2021 Author Share Posted March 14, 2021 Thanks John, I can’t level my coach where I am but am moving Monday so will check tranny. When the problem started I was climbing hills and might have been in economic mode but it was stuttering before it shifted. As I got out of the hills it shifted better. I will check the fluid when level. paul Link to comment Share on other sites More sharing options...
Gary 05 AMB DST Posted March 14, 2021 Share Posted March 14, 2021 Also check your coolant level. Gary 05 AMB DST Link to comment Share on other sites More sharing options...

vito.a Posted March 14, 2021 Share Posted March 14, 2021 You need a heavy diesel code reader to check the ECU codes. Usually when the light comes on going up hills its an EGR system code. Link to comment Share on other sites More sharing options...
Paul Busch Posted March 14, 2021 Author Share Posted March 14, 2021 Thanks Vito, I am in Rv park Livingston Tx and mobile tech wanted 900.00 to come out and read codes. I am heading to San Antonio in a couple days and will see if I can find someone there. paul Link to comment Share on other sites More sharing options...

willbo777 Posted March 15, 2021 Share Posted March 15, 2021 Try replacing the coolant sensor in the overflow tank. That has fixed the same problem for me several times. I usually get a few years out of them. Link to comment Share on other sites More sharing options...
Paul Busch Posted March 15, 2021 Author Share Posted March 15, 2021 Bill, I will do that when I get to San Antonio. That would be awesome if that is all it. I hope. paul Link to comment Share on other sites More sharing options...
Paul Busch Posted March 15, 2021 Author Share Posted March 15, 2021 Bill, I have a Detroit series 60. I don’t know what you have but do you have a part number? paul Link to comment Share on other sites More sharing options...
willbo777 Posted March 15, 2021 Share Posted March 15, 2021 Yes, I have a Detroit Series 60. The only part number I have is DD 23520380 Link to comment Share on other sites More sharing options...
Paul Busch Posted March 22, 2021 Author Share Posted March 22, 2021 Bill, I did get the part you suggested and just installed it. Same engine light still on. Is there power to this that I can check? Ground or 12 volt positive? I know the level sensor was the plastic one that Monaco used so I was hopeful. thanks Paul Link to comment Share on other sites More sharing options...
