Hi, Well I haven't been able to long ride my '04 C5 Verte since I bought it 6 months ago, just putt around town. So yesterday I took it on a Sunday cruise and half way through the engine light illuminated. Talk about a total let down. But my spirits are high. Now, owners, be patient with me as I am only just a little bit good at fixing things. So I went to o'erily's and they ran a diagnostic which came up with one error, P0332. Now I have done some research since last night and here is what I think. Please correct me if I am wrong or need more stuff and/or information as this is my baby and doing my first operation needs to be a total success. But I need GM OEM numbers and cannot find them. The local dealer only says they have the parts but won't tell me the numbers.
So here is what I got so far;
1. Both knock sensors are the same number, do they need to be OEM parts to make sure detonation is perfect (or can I use the BWD S8696?), and I should replace both even though only 'bank B' has the error? What is the OEM GM part number?
2. I need to replace the interconnecting harness for the sensors. What is the OEM GM part number?
3. When I replace both grommets for the knock sensors I need to make 'wall' the grommets of about 270 degrees to prevent moisture from getting into the knock sensors. What do I use?
4. Do I order a set of new gaskets for the intake manifold, if so what number? Do I coat the gasket with anything on both sides before I put them back on? What is the OEM GM part number?
5. I don't have the money to relocate the oil pressure sensor, but should I replace the sensor while the manifold is off? if so, What is the OEM GM part number?

Did I miss anything? I need to do this today as I am under water without it, I need to get to the VA in 4 days and it is my only mode of transportation. Thank you everyone.

 

I don't have parts numbers for you but I can tell you what I did when I replaced my knock sensors. I got the Delphi knock sensors and Felpro gasket set from Napa. They also sell the harness there but I got mines from the dealership. The harness will come with the grommets so you don't have to get those separately. I replaced the oil pressure sensor with a Borg Warner part, also replaced the o ring on the cam sensor. I did not do the silicone dam thing. I figure if it last another 100k miles I'm ok with it. This was about 2 years and 40k miles ago and alls been well. I don't wash my engine anymore for fear of damaging the knock sensors. Good luck getting yours fixed and running.
