there are a couple of reasons it could be, it is possible that the sending unit is bad. It could also be the instrument panel cluster or the PCM, there are some reflashes for the pcm for this issue but you would have to find a dealer or an independent repair shop that has the snap on online programming set up. most of the sending units go bad in these and if it is this there is a newer design from GM for some models
