I had a check engine light and codes say that I need to replace the O2 sensors after the CAT.

I can buy the sensors online for under $100 each. (2 required)

anyone know how to install the O2 sensor for 2000 E320 sedan?


thanks

They should just thread right in the the exhaust after the cats. Get it up in the air and find the orginals ones, unplug them and unscrew them. See if you need thread sealant before you put the new ones back in or take the originals out for that matter. Then plug them in.

You will need the special O2 sensor socket....It makes the Job a LOT Faster!
