Bought the new to me car in September.
driving one day and the oil pressure sensor came on and car went into limp mode. Put the car in park turned off and sat for a minute. Restarted just fine. No check engine light.
Replaced switch. Ran fine for a week. Did it again. Replaced switch. Ran fine for a week then started dumping oil from the switch.. and limp mode. Finally they put a Chrysler part in not aftermarket. Guess what. Ran fine for a month. Driving and limp mode. It just got towed off to the shop.

What the heck is causing this to happen ?! No check engine light no codes.
