Code SPN 5246 FMI 0 Derate
I've got a problem with my ISC 380 Cummins. It has a check engine code SPN 4363 FMI 3 which is "Open or shorted SCR temp sensor" and when I pulled into the RV park it set a SPN 5246 FMI 0 stop engine ...

If you clear the code (and the derate) without fixing the SCR temperature sensor, don't you run the risk of damaging the exhaust system, turning a sensor replacement into an expensive SCR replacement?
Any answer other than "tow" seems like it could cost you a lot more than the 5 mile tow. (which could be "free" if you belong to a roadside service club)
