Oil pressure unit
Hey hoping someone could give me some advice on what to do.
So when I bought my c5 from this used car dealership a month ago a stipulation of me buying it was having them replace the oil pressure sensor and or gauge, since the gauge was pegged at 80 and cluster read 130. I got this in writing from them.
Dropped the car off to get fixed and they said they couldn't fix it because they think it's an electrical issue and they made an appointment to take it to a electrical shop next week. The reason they said they think this is because I don't have power to my driver's side door control. They said "that they could be related" even though I lost power to my door on the way to drop it off, ironically.
My question is could they be related? Or are they just bs'ing me? Thanks for the Input.

Not related. The oil pressure sender is a known issue. When they fail it typically shows max pressure.
The correct way to replace the sensor is to remove the intake manifold. There is a small vacuum line that is a bit short to get reconnected easily. It is best to add a bit of extension to it during the reassembly. In doing this job I would also replace the intake gaskets since they are probably the originals and at best are 15 yrs old.
As to the door issue, there is a wire harness that goes through the door to the chassis. The pins in the connector have been know to get corroded and have lesser contact over the years.
There are many posts on both of these issues.

Based on advice from a few sources I went with the "BWD S4202" oil pressure sending unit. You'll know it because it's one of the few that comes with thread locker. I've heard that the newer AC Delco units aren't the same quality as the originals. Just wanted to add this incase you end up doing it yourself.
If you end up doing it yourself it's not a difficult job, and you'll get to know your car better. Goodluck!

The "linked" claim sounds like BS.
But just replacing the current oil pressure sensor with a new one does not mean the issue will not soon return. I went through three in a year until I did the relocation and haven't had a failure in over five years.
