My check engine light is on. The code I retrieved is for the upstream oxygen sensor. It's a 2003 Galant 4 cylinder. Can someone post an image of the exact location of the sensor? I would really appreciate it. Thanks.

your repair manual does not show it ????

 

It does at close up, but for the life of me, I can't find it.

 

its attached to the exhaust system. there might be 2 of them

 

There is one in front on the exhaust manifold....bank 1 and the second is underneath the car before the catalytic converter... bank 2
