Default High Oil Pressure Indication

My C5 is showing it is pegged on both the analog and digital reading guages. I am not over heating and I am sitting at about 56% oil life? What's up?

Default oil

Bad oil pressure sending unit, common problem on the C5's.
You will need to replace it. It is located under the intake by the
firewall. As far as I know you have to remove the intake. There
have been some posts on a remote location, you will need to do
a search.

Here's some info to help you do this fix yourself:

1) Here's the thread for the step by step how to:
http://forums.corvetteforum.com/show...ght=change+oil
Pay attention to the little extension tube for the vacuum straw behind the intake.


2) Here's the link to post 272 which is a step by step on how to do the oil pressure sensor relocate which you'll definitely want to do in case your replacement sensors fail. This gives you easy access in the future without having to remove your intake again. Most use the Buick sender since it's still brass. They don't make brass ones for the vette anymore and it works just fine in this relocation scheme.

Let me know if you need any help on details. Do yourself a favor and skip the "cut a hole in your vette" method. Keep her intact and look at some of the misadventures of others in doing this.

Default Bad Pressure Sensor

I had the same problem on my 97. I used the
" cut hole " method and if I ever need to replace it again itl be a piece of cake . Way better than pulling the intake and the problems that can be created there. look
for detailed thread on replacing sensor . I bought mine at advance for about 40.00. Being extra careful and taking breaks took about 90 minutes.
Good Luck

I suppose you are right, demolition is easier than construction.

Funny, mine just started this a few days ago. Was reading real high for about a day, and is now pegged at 130 psi.

Well, I wouldn't buy your car if I knew you cut a hole in it just because you were to lazy to pull the intake manifold and do it correctly. The way I figure it, if you would cut corners ( and holes) what else would you do?

No biggie, plenty of guys don't even know what to look for when they buy a vette, no one will ever know.

My made in Mexico aluminum housed replacement sensor now has 13K+ miles on it...
follow the instructions in berryj's post or in Vectoz DIY ( search archives, C5, Id Vectorz and keywords oil pressure sensor) make SURE there is NO residual oil on the electical connectors and that you torque to EXACTLY 15 ft-lbs

13K is pretty good! Hopefully it will continue to keep on being faithful.

Oh, my first link posted above also has a link within that post to the VectorZ write up for those looking.
