  Hi,
  When your dealing with an oil pressure light, it is a good idea to have the oil pressure checked. You can perform a visual check of the wiring to the oil pressure sender first, but if it is ok you should rule out a low oil pressure situation before moving on to a gauge problem.

  Replacing the sending unit should do the trick

  It is very easy to diagnose this problem.
  just remove the oil pressure switch and hook up a gauge. If the pressure is good,
  then you know the engine has no problems, now check for a gauge or wiring or switch problem.

  My wrangler oil gauge use to read in the middle of the gauge. Now it is pegged out on the high end. Everything else seem fine. Oil is full and is running fine.
