648 question
« on: September 11, 2014, 12:20:13 PM »
My 648 Glll is throwing a f475 and f478  and I checked the plug wires and there are one little nic on each wire... would that's cause the machine to throw that code? It comes on every now and then and I have to shut it off for a few minutes and after a couple trys it goes off for a little longer.....thanks for any help

f475 is low engine oil pressure.  Yes, if the wires going to the oil pressure switch are damaged   I don't have my laptop with me, But I think the other code is an engine derate code due to the low oil pressure, But I am not 100% sure on it.
