I replaced the oil pressure sensor and am still having the same problem of the oil gauge dropping to zero when coming to a stop or sitting at idle. So what is next??? I have also read that the oil sending unit could be bad, where is this at in the oil pan? I have called a couple of shops that do basic work on our company trucks and they have all told me to take it to the dealer to find the problem. You know the end result of that, $$$$$$$.
