Do you have a diagram or tell me where the location of the oil pressure sensor is on a 1989 Chevy Corisca.
I have a very low oil pressure gauge reading which does not move up unless you rev the engine. What is the problem.

For the 2.0L engine the oil pressure sender/switch is under the intake manifold, at the right rear of engine. For the 2.8L engines it is near the oil filter, at the right front of the engine. Place a "T" at the sender and use a manual oil pressure gauge to test pressure. If it shows same as the instrument panel gauge then suspect faulty oil pump. If it shows good then suspect faulty oil pressure sender/switch.
