Jbw92 Posted November 28, 2021 Share Posted November 28, 2021 P009B P026C P016F 247-FMI 14 these are the codes I’m getting from a scanner.. I’ve looked some of them up with no luck of a solid issue. Can anyone help me out? Truck has no power. Turbo under high load makes a squeal noise more than a whistle and rough idle.

0 Onyx610 Posted November 30, 2021 Share Posted November 30, 2021 Anything been done to the truck before these codes came up? Looks like from some quick looking around these are mostly fuel codes? One I see is for the fuel pressure relief valve, I would start there as that could be the cause for majority of these codes and the rough idle.

I did see one of the codes is a software update code. The post said it affects all I have happening, going to get it to Mack and see if they can do whatever update they made. Then go from there Quote Link to comment https://www.bigmacktrucks.com/topic/68842-mp8-engine-codes/#findComment-484136 Share on other sites More sharing options...
