What Would Happen If I Installed This Sensor In My Gn

You would have a nice new signal for the computer - it's fine, run it.

so why does the search onTB tell me 20 and 22 gnx i am confused,COULD it give false readings on scanmaster for 02s and blm???????? at idle

 

[Blown&Injected]

Oh man - maybe I'm messin' up.

I thought the 21 is the GNX sensor.

Does it have one purple wire?

 

[turbo nasty]

AC delco sensors have the purple wire. The afs22 is the GNX one, get that if your getting

Better search again because it looks like I was correct in the first place...

I just looked and Razor says the 21 is the GNX sensor and another board member listed GM part numbers that matched the detailed PN for an 87 GN with afs20.

There was good detail in the post that called the 20 the GN sensor and if Julio calls the 21, the GNX sensor, I've got to believe him.

Interesting. I've been running a 21 in my 87 for over 12 years now. Still works perfectly.

Wonder why the engineers skipped the 21 and went with the 22 on the x project??

And that is a strong argument!

I am fairly certain that I just put a 21 in and it is reading great!

As I commented on Razor, based on his reputation, if I were to make up a name for TurboDave, it would be, The Tune Master, based on all his posts that I have read. So if he likes the 21, that says a lot...
