Blew a lifter, had it replaced and honed out all put back together have a new oil pressure sensor and still getting a low oil pressure shut off engine message. I’ve checked the oil everything is good. Any thoughts???

Are you able to hook up a mechanical gauge to be sure? If your pressure is good, could be a bad sensor which is located behind the supercharger.

I just switched out the sensor, still getting the same problem. Turned the car on and let it idle and it fell and came up with the same message

The factory setting for that message is if it drops below 5 psi or so at idle. Which is extremely low.

I’m guessing it’s all the metal in the engine still that’s causing the problem
