Hello, this is my first post on here. I have been searching all over looking for answer and found none. I recently bought an ‘08 impala SS, and rebuilt the motor. I got everything done and started up and warmed up the car and when idling the low oil pressure light was coming on. I racked my brain to make sure that i did everything correctly when putting the motor together. I was checking to make sure i plugged everything in and underneath the motor on the oil pan there is a sensor unplugged and i cant remember if it was plugged in to begin with. I believe it is the oil level sensor. I replaced the oil pressure sensor when rebuilding the motor, so that should be fine. Im wondering if that sensor being unplugged could give me low oil pressure warning.
