Changing the Oil Pressure Sensor
Hello fellow Corvette lovers. I wanted to let everyone know how I ended up changing my C5 Corvette oil pressure sensor which was a lot easier than the procedure in the Service Manual. The SM says to remove the intake manifold which would be a real pain to just change a sensor. For those who do not know, the pressure sensor is located in the rear top of the engine under the windshield wiper motor plastic housing. I decided the easiest way to change the sensor was to remove the windshield wipers, remove the top cover and cut an access section out of the bottom of the housing using my dremel tool. I cut a 3 inch by 6 inch section directly above the sensor and it was really easy to access the sensor and remove it. The access area that was cut will be covered up when the wiper motor cover is put back on so now I have a easy way to replace the sensor without much effort. The engineers at Chevrolet should have designed this in but then I remembered that the dealership service department charges by the hour so the longer it takes the more they make. Hope this will help others and I will try and post pics tomorrow.

It provides an opportunity to clean and inspect under the manifold and replace old evap lines and manifold gaskets. I don't see the cutting method as being a huge time save once you factor in the struggle of getting the connections on and off the sensor.
I don't think an owner's modifications is "butchering" the car, so long as things are done properly. Any modification or repair that cuts corners when the "trade off" is so minimal should be discouraged. It would be like a mechanic cutting a hole in the undertray to get to an oil filter. Yes it saves time, but isn't the way to do it.

since you asked no, it refers to cutting a hole in the cowl to replace a part. Its really not that hard to pull the intake and replace the sensor

Without seeing how it was done and the final result, just do not agree with the butchering comment. But now it is time for my daily stipend of beer. Cheers.

Thanks for sharing, I believe most people already know about that option but I am getting ready to change my sensor and I see this as a good opportunity to get in there and clean up the motor a bit... Also, will be replacing manifold gaskets as well.

I still don't get this hack or why people are proud of the time savings. The intake on a LS motor is easy to remove and re-install. I can get the intake off in a similar time to removing the wipers and cowl cover. And yes, needlessly chopping a hole in the car is what I call a hack or butchering the car.

I made this one when I changed the knock sensors on the Fbody. Basically identical procedure, only difference is no throttle cable and you can remove all but two bolts on the corvette, Fbody has 4 that wont come out.

Many videos on the subject on YouTube. Here's one where you don't have to cut off anything:

I'll bet this is the method employed at the dealership... most shops pay the techs based on production. 'Flat Rate' book labor time is billed to the customer, based on steps called for in the service manual. Any short cuts that can be used will increase their salary!
I've gotten lazy in my old age, and find it simpler just to remove the intake and skip all the bullsh*t.
