Hi,friends,doesnt show pressure on the Gauge,sometime see some movements on the needle,thinking bad sending unit,loose cabel(maybe).Where is that thing under the Hood ??.thanks Thomas

 

underneath the oil filter housing.

 

Sleepwalker is correct on location of oil pressure sending unit. If connections look good at sending unit, options should be the problemis either the sending unit, wiring, or the instrument gauge cluster. Just replacing thesending unti may not fix the problem. If you have a digitial odometer, with a little time/patience you can diagnose whether to take next steps on replacing repairing the instrument gauge set.Let me know if I can assist by sending an IM and I can reply withan attachment of basic instructions on using the test mode functions that can be presented by pressing the small button inside the clock adjust ****.
