Derate to 5mph crisis - regen not clearing codes for some reason

Just call em !

 

I wouldn't give a #### about what logs thinks as long as your legal.

When I added the second truck, I let the driver take mine for two weeks until I got it put on the fleet. I didn't log out of mine, and it gave us both a violation every day for two weeks. And they can't fix it, it's a glich in the system. But #### if they didn't have us sign our logs anyway and say "Don't worry about it."

So I approved my logs for two weeks saying I was all over God's creation, when I was in Phoenix.

F the log department.

And they are just now falling off. Been looking at them for 6 months.

 

Really bad idea. Especially after hours.

 

I know if I'd known about that speed sensor trick, Casper never would have seen the hook, if removing it works.

 

If I was them I would be happy with a little log editing over a $5000.00 tow bill!

 

I can help you to clear that stupid regulation code and get normal speed. Do you have diagnosticlink with you ?

 

ok. you need to go under truck and remove NOx outlet sensor. just remove it from 1 box but don't disconnect the wires. Close the hole with M20 bolt. Or you can buy a new Nox outlet sensor and connect that one to the harness. Anyway NOx outlet sensor must be in air and ACM must get signal from that sensor. When you run parked forced regen ACM will have 100% nox conversion. Do back to back 2 parked regens. Clear the codes. If derate code will come back, drive the truck about 1 mile and derate code will disappear itself. Your engine has nox conversion problem or one of the nox sensors are bad(or inlet nox sensor is sending lower value, or outlet nox sensor is sending higher value).
