actually the 05s from the factory are the only year to have a real pressure sending unit and not just a pressure switch so when yours was working it should have shown a difference in pressure from idle to driving. if your not the first owner maybe the unit went bad and was changed at one point with just the pressure switch unit05' Frontier's have dummy oil gauges. If the truck has pressure at all then the guage will read normal. If it doesn't have pressure then it will show low. Mine has been out for 6months.
dealerships are good at that, with most people it tends to work for them with just about everything. i think they train them to say "its normal" to just about anything too hehVery good point. I did buy it used so that could be the case. Dealarship told me that the 05's were dummy gauges but he could have just been trying to get my off the phone.
Did Zero_Six_LE have this issue a few months back?I have an 05 Nismo. My gauge used to work great (read the true pressure), but now it reads at the highest level ALL the time. Anyone have any idea why?
More than likely the OP sending unit failed... check wiring, replace.. should be cheap, likely hard to get to LOLI have an 05 Nismo. My gauge used to work great (read the true pressure), but now it reads at the highest level ALL the time. Anyone have any idea why?
