dcrow Posted February 1, 2017 Share Posted February 1, 2017 The other day my engine light came on and when I got the codes off of the odometer it says 5277-05 and under that !M 128. Any ideas what this is? Quote Link to comment https://www.bigmacktrucks.com/topic/48587-2007-chn-engine-code/ Share on other sites More sharing options...
Mackpro Posted February 2, 2017 Share Posted February 2, 2017 (edited) That's a SID-277 FMI-5 sadly I don't have my book with me to tell what means. MID 128 means engine though.

dcrow Posted February 3, 2017 Author Share Posted February 3, 2017 Ok I did a google search of SID-277 FMI-5 and found egr mass flow open does this mean the sensors are bad? I did just have all of the egr components off so I could clean them. I checked and the plugs are in. The only real soot I found was in the cooler, the mass flow tube and intake were black but no amount of soot on anythnig else.
