I had to replace the connector for the sensor and in the process I checked out the seal on the sensor and it looks like it needs to be replaced.I can't seem to find anyone who sells just that piece.Would my local dealer have it?Thanks

 

If your talking about the green sensor plug, you can possibly find a similar harness at your local auto parts store. I know they won't have the exact harness, but they do carry a variety of electrical harnesses with the weather pack seal on them, maybe find one thats comparable size and just use the seal thats on it.
Otherwise, might try someone like www.casperselectronics.com

 

He already replace the connector.... I think he needs the rubber seal that seals the nipple on the bottom of the MAP sensor to the hole in the intake manifold. Should be a fairly common part, since similar MAP sensors are used on many vehicles.

 

Yes, all I was saying is buy a harness connector with the seal on it and remove the seal and use it on his connector. I know they have several different pigtails in the HELP parts section, they don't have the LT1 one as I've needed it before, but there's several connectors similar in size. Usually around $5 or so.

 

He is not referring to the connector seal.

GM PART # 1635948 for the MAP sensor seal.

I don't think its the seal on the connector. Its the seal that goes between the MAP sensor and the intake manifold - prevents a vacuum leak. I think its orange.

 

Oh I see from sb pic. Never had a need to remove the entire sensor, never knew there was a round rubber seal in there...I'll go back in my corner now...

 

Thats it. I think I found it at gm parts direct.Doesn't show a picture,but the part number matched.
