does anybody know where the heated oxygen sensor goes.... i took it off and now i dont remember where it goes.... if you have pics that would be greatly appreciated.....

 

in the exhaust manifold

 

wait thats not the part... sorry.... i cant post pics cause i dont have a camera... but its like this solenoid looking thing... and it has this black cap on it with 2 wires coming out of it the colors are blue and black w/ yellow stripe and into a plug.... is it like a pressure valve or something.... it goes somewhere behind the block...

 

Sounds like maybe the MAP sensor,goes on the intake.

 

what motor/car is it for?

heated o2 sensors have 4 wires i thought...and no 'solenoid'..

 

Thats your eacv, it plugs into the rear of the intake manifold close to the firewall.
