New code came up today on my cm870. 2270 which looks like egr position sensor low voltage or short. Don't even know where I should start with this one. Google says replace egr valve....wgat do the great minds on rawze.com say?
I've checked connectors and followed wires to the harness. There are two sets if wires one for the stepper motor one for the position sensor. Truck is not de mandated and all the sensors have been recently cleaned.
