Default C6 Oil Pressure SENSOR GONE BAD! 80 PSI CONSTANTLY!

OK SO I GOT THE DREADED 80 PSI reading on my car and it merely sticks there when turned off and back on. I know that this most likely indicates a faulty oil pressure sensor. I checked the oil level an it is fine. I did the search on this forum and I got the C5 DIY. I was was wondering if anyone knew a step by step for a C6???

Would greatly appreciate it. Otherwise I have to drop the car off to the dealership...

And I really hate being without my car.

Also does this problem EVER just go away. Or is it most definitely a replace deal?

I just had a faulty sensor replaced. However, mine did not read 80 psi, mine said "faulty sensor." Discount tire put one on for something like $55 installed (not positive on price, but it was reasonable).

I've heard that if you reprogram the sensor sometimes it will start working again, that's worth a try. A good tire store or your Chevy dealer should be able to reprogram the bad sensor.

Otherwise known as the OIL PRESSURE Sending Unit. Which apparently sits behind the intake manifold.

I have been doing a lot of reading here. Is the procedure the same as that of a C5??? I am curious if the C6 is easier to reach? ANYONE?

Check out the postings in the C6 Tech forum. Recent discussion on this very issue. Sounds like a deep socket and a little agility is all that is needed but then ............

I remember it being a difficult process on C5. Some advised replacing with the remote unit set up. Does that not also apply to the C6?

I don't think agility has anything to do with replacing this monster.

You have two choices:

1) Remove the intake manifold and gain access to the top rear of the engine

2) Dill or cut a hole in the plastic cowling under the wipers as show here http://forums.corvetteforum.com/1558850078-post7.html


With my supercharger sitting on top of my engine, I can guarantee you that I am going to use #2 if my sensor takes a crap.

Yes my third option is warranty. If this is a really big problem then I would maybe submit to dealership.

It's common across the entire GM LSx vehicle line

I'd do number 1, taking the intake manifold off is a very quick & easy job.

Default oil pressure sensor

Did you ever get this done on your car? My pressure gauge is pegged and I have to change my sensor too. The only detailed drawings I'm finding are for the C5. I do not want to start cutting on my car to find this little part without a little more help.

Thanks!
