Most likely cause is a failed oil pressure switch. It will probably have oil leaking into the connector. On a 4cyl it is on the back of the block.. On a V6 it is next to the oil filter.
make sure gas cap is on all the way and drive it a few tanks and see if it goes off by itself.
Your brake fuild might be low.
Alternator defective, or alternator belt broken or slipping.
Alternator is not charging the battery
Bad sending unit, low oil, low oil pressure.
You should check your fluid levels, your oil and coolant.
There are three or four retainers from inside the trunk. You then pull the light rearward.
That means you need to get toa gas station.
Not that I know of. The oil pressure light comes on at a very low pressure, but it will not shut the car off.
the bulbs on the tail lights should twist to the left and the light socket itself should come out then the bulb should also twist out to the left of the socket or on some cars u need to unscrew the red light cover itself and you will see the light sockets attached to the light bezel
In the trunk directly behind the tail light pull the carpet back and there are three twist off plastic nuts take them off then pull tail light straight out
Until you run out of gas...
