AEM wideband probleme

[joneSRT]

I have a problem with my AEM wideband since day one. Here is a list of the steps I’ve been thru so far:

1- Installed the wideband for the first time: I can only read 11.3 or 14.7 all the time….it is not moving.
2- I changed the sender…..still doing the same thing.
3- I installed my buddy’s AEM wideband (which is working perfectly in his car) in my car… still doing the same thing.
4- I installed my AEM gauge in my buddy’s car….. still not working and doing the same thing.
5- We compared the colors of the wires between my gauge and my buddy’s gauge and the pink and green wire were not at the same location. We switched the pink and green wire on my gauge. WOW it is now working!!
6- This was too good to be true. Now when I start my car in the morning….my gauge is working but as soon as the temperature build up or I get into boost….it is not working like at the beginning. I can now read 11.3 at idle and it will move as I drive with the car. The gauge seems to work but like 3 pts offset (low)!!

This is freaking weird and I don’t know what to do and think. Any wideband experts around here?? Any help would be appreciated.

Im very curious as to the solution to this problem as well..Mine does the same..Will not come off 14.7 no matter what...

Found solution..
Called AEM..They said its the O2 sensor..Replace it..Make sure its in the exhaust and at a 45 deg angle towards the turbo..
