My check engine diagnostic test came up with a problem in the "baro sensor circuit". The probable causes the book provided are bad wires/connections going to the ECM or a bad Baro sensor.
So my question, is the baro sensor the most probable cause? What does it do and where is it? Thanks

 

sorry for the bad pick , but the baro sensor is the sensor located in this location(circled in white) if you dont know what it stands for it is the barometer sensor and it tells the car the atmosphereic pressure so the fuel curve can be adjusted accordingly.

 

i think, and am definently not for sure, that there is a vaccum line going to the sensor. make sure it didnt get dicontected. make sure the harness is snug on it.

 

I think i found the Baro Sensor but it is not where the book said it would be so i attached a pic to make sure i am on the right track.
Assuming what i am looking at is what i think it is, all the wires and the vacume hose look good. Is this a sonsor that commonly goes out? Is the price low enough that i should just replace it to see if that fixes the problem? Thanks a bunch!

 

can you post one a little farther off. im not sure what im looking at. i believe it is around there but a little higher.

 

that actually looks like the one, but i would get more advice first because the sensor isnt cheap, its like 50 bucks or more.
