Just went through similar situation... Changed opsu, than I checked with a mechanical gauge and was still having same issues. Put new pump in and still same problem... My engine always ran dead silent though so IDK!

That sucks! I hope the sensor will fix the issue .or i might aswell start saving for new motor..

I turned car back on after letting it cool down.oil pressure came up fast was at 40 then reved it up no more than 3k and oil pressure increased to 60 65..im hopeing its just opsu sensor messing up..any thoughts? Everyone

Sounds like its the sensor to me, being you hear no weird noises, and the oil pressure being fine.

try the opsu first. if that doesn't fix it then you have bigger problems and I would stop driving the car until you get it resolved.

What else do you want to hear? Go change the opsu and you will have your answer... It takes 30 mins to change. Go to orielys and get the special socket that goes over the sensor and you can just get over to it and remove and reinstall it. Or just pull the intake. Witch takes a bit longer, but still very simple...

I had a very similar issue with my SRT4. The SRT Autometer OPSU was faulty and actually leaking oil showing me 4psi-0psi at warm idle sometimes.

I changed the OPSU and with no leaks have upwards of 100psi on cold starts and nothing lower than 20psi at idle.

You should really change the OPSU as suggested, or buy a mechanical OPG to test the car if you are in a hurry to drive it.

keep driving it. You will find out soon enough if its the OPSU or not.
