this is not an ss, since i sold mine a couple years ago (miss it very much) but thought someone here could help. i have an 04 silverado 5.3 and the oil gauge stopped working. the needle is all the way to the right and does not move at any time. is this the pressure sensor or something else? i have checked the oil and it is full. there are no other idiot lights illuminated. where is the pressure sensor located on the 5.3? any help would be nice. Thanks.
