How do I replace the front oxygen sensor on a 96 Accord (code PO141)? How hard is this to do? Any special tools required? Thanks, guys!

 

Its very easy, and very visible because its almost in front of you when you pop the hood. You need a 02 sensor socket and wrench. After you install, clear the codes and youre all set. Advisable to get OEM o2 sensors not the universal kind.

 

IIRC, you will need a really big cresent wrench. Obviously a socket won't work. I used a really big pair of pliers because I didn't have the right size wrench. Also, you will need to move the heat shield out of the way. Big pain to remove it completely--just loosen it and move it out of the way. It's an easy and obvious repair. You might put a little anti-seize on the threads.
