2011 Chevrolet Silverado 2500 HD LT 6.0L MIL Lamp on VIN: 1GC2KXCG5B
P2161: Vss b. the freeze frame is showing mph when it sets the code. that is what is very odd. I am not sure what the vss b circuit is? I have read where the vss sensor had been changed and the code came back. could it be using another sensor?
