After getting a oil change, I noticed the oil pressure stays a little higher than 40. What should I check for this. I been always using full synthetic. Where are all the electrical wires that control the sending unit and everything that works with the oil that I could check as far as electricity and everything else that could cause the pressure to slightly rise.

 

I don't see a problem with the pressure being a little over 40 psi.

The sending unit and wire for the gauge is on the right side of the engine near the oil filter. There's a small oil pressure *switch* for the warning light and a larger unit.....sorta bell shaped or dome shaped....for the gauge.

My car runs about 50psi warm @ 75,000 mi. Sounds normal to me.

 

You can remove the oil pressure sending unit and screw in an analog pressure gauge to find the correct pressure reading.

 

With clean new oil i get 42psi at idle and 65 at speed
