| RE: Fault code 3751 can take up to a hour. that code basically means your SCR is not working. it measures nox inlet and outlet and its seeing its not reducing nox enough. that is a very serious code which will come with serious derates after about 50 engine hours if it not solved. It can be nox sensors, bad scr, exhaust leaks, bad urea injector, bad urea, bad urea pump, etc, etc. that is not a nuisance code its your truck telling you its scr isnt working. | |||
