I did search on this one but i cant find the answer

i have a p28 usdm in my car and im getting my p28 edm (is the same as a jdm p2 to get chipped but the only difference except for the number after p28 is the thing in the red circle... what is it supposed to do


i took the image on pgmfi.org but they have the same question i think...

 

You just answered your own question with a picture.

Its the PA sensor. Have no idea why it isnt used in the JDM/EDM ecus.

 

yeah, you can disable that and injector test in uber anyways

 

probly cuz its mounted to the car somewhere....like on some EF's and tegs...
