where is the OIL PRESSURE SENSOR ON A BUICK RAINER

Asked by May 15, 2013 at 01:06 AM about the Buick Rainier

Question type: Maintenance & Repair

What would make my oil gauge jump around from zero to 80 and back to zero again.

2 Answers

It is indeed at the front of the engine bay and mounted to the engine block about 6 or 7 inches to the right of the oil filter (looking into the bay). It's buried low and out of sight, just under the exhaust manifold.

A wire that is disconnected from the sender and occasionally bouncing around and making a ground connection would make your gauge act in the fashion you described.
