how to replace and oxygen sensor on a 1993 honda accord ex

Which one are you looking to change?

 

Customer: replied 6 years ago.
The oxygen sensor

There are 2.

 

 

Customer: replied 6 years ago.
I did not know this I only purchased 1 are they both the same thing and where are they located
Expert:  Ron Z. replied 6 years ago.

 

They are not the same and not interchangable. I would strongly recommend you find out which one needs to be replaced, as installing the wrong sensor will cause problems. And replacing the wrong sensor will get expensive. I can give you locations, and the procedure is the same for both, but like I say, find out for sure which one is faulty. One is located in the exhaust manifold under hood, the other in the exhaust pipe under the vehicle.
