Oil Pressure Sensor
When I drive my 88 Corvette, the oil pressure always reads 80 psi on the digital dash, and it never changes... whether idling or driving at higher speeds. I believe that the oil pressure sensor is bad or possibly corroded. Can anyone tell me where it is located on the engine?

When you decide to change the sensor, you may consider changing the switch too (the short one, at about 45 degree angle) since you will be in there. I changed mine last week on my 91 L98, and I must say, it was a bear getting to the sensor. I originally planned to change the switch because it was leaking up through the switch out of the electrical connector. I bought a sensor at Pep Boys and changed it at the same time. Now my oil pressure drops to zero at idle after it gets hot. Point being, I should have bought an OEM sensor! To gain access, I pulled the distributor cap, pulled the plug wires out of the way, loosened the intake tubes just so I could get a 1 1/8 inch wrench on the sensor. The switch will come off with a 1 1/16 deep well socket.

Because I was in the area since the switch was leaking, I thought I would be a little pro-active. I believe it is a dura-last (auto Bone). I'm thinking about going to the Dealer to get an AC Delco sensor. P.S. My drawing shows the switch as the short one (one wire). Is that not right?
