2002 Chevrolet Silverado 1500 4x4 with tow package, had the abs light come up, it is a C0225, EFI Live says open rear abs sensor. I cannot for the life of me figure this code out. I have just went through the entire truck replaced everything, flushed the engine, transmission and rear differential, new air and fuel filter, new bulbs, i went and got a new ABS sensor for the front because that's what i thought it was, but now it's not. Hopefully parts shop will let me return it, as it was $75 and i dont need it. Anyone know how to fix this C0225 ABS code?
