Hi,

I think my oil pressure sensor died yesterday. I looked down and saw it reading at max. Checked the info center and the reading was 82 at idle and 90 plus driving. After turning the car off it was still 54 so I'm pretty sure it's bad.

Looks like I have this in my future:

I've heard the cut method can leak water so I'll try using a socket. If not probably take the intake out. That doesn't look too hard but I am worried about the wiring. It feels pretty crispy.

While I'm in there anything else I should work on?

Thanks!

 

What year and trim of your car?

If it is a manual transmission GS, that oil pressure is normal especially if the oil is not fully warmed up. It is because it has the dry sump oiling system.

 

Your concern over the wiring is valid.
When I started to remove the intake manifold on my 2009, I broke 2 of the plastic connectors and then stopped.
​​​I then ordered new connectors for fuel injectors, new harness for the coil packs, as well as the connectors for the main harness that plugs into the coil packs. I also ordered some electrical tape made specifically for under-hood automotive use.

These cars create and hold a lot of heat under the hood and I do not think the fuel rail covers are helping any, all the wiring beneath them was "crispy".
So, the electrical work turned into more of a job than replacing the OPSU.
I started by removing all of the factory electrical tape, I then found that most of the wires under the electrical tape were starting to fuse together from the heat. After gently peeling the wires apart and inspecting for damage I removed and replaced the plastic portion of all the connectors. Most of the metal pins inside the connectors seemed to be good, although I did end up replacing a few that were damaged by my handing. I then rewrapped the harness, vacuumed up all the crispies and then went on to remove the intake.
Not too difficult, there are several videos out there that will tutor you on replacing connectors and what tools to use.
While the intake is off take a good look around for leaky gaskets, at over 100,000 miles I replaced valve cover and valley cover gaskets just to be proactive.

 

I've gotten stuck on this. I got a 27mm socket from HF but can't get it on the sensor.

While on the C5 there's room back there on the C6 the firewall seems closer and there isn't enough room to get the socket onto the sensor. When I try and put it on it gets stuck between the firewall and the intake. Is there a way to do this on a C6 without removing the intake? I don't see a way.

I've taken intakes off before and it doesn't look too hard but I'd sure like to save the hassle.

 

I know someone who just did this, and it worked out real well.
Cutting and repairing a hole really is the hot tip. I'm always concerned with breaking old, heat hardened plastic parts.
