I am unable to remove the rear oxygen sensor on an 01 accord.
I am cranking the wrench hardest I can but it wont budge.
any tricks, would it be an idea to remove it when it is hot?

thanks

 

get a full exhaust lol

 

take heat sheilding off then get two wrenches of coarse one that fits the size of the O2 sensor i cant remember off hand, interlock the wrenches(wrench trick) hit with a hammer to loosen up, soak with pb blaster first though.

 

Ok, will try that , thanks alot

 

also try heating the exhaust pipe around the 02 bung but dont heat the o2 sensor.... the trick is to get the pipe to expand away from the sensor
