Hey! I have a 1998 toyota corolla le 1.8L. I'm trying to replace the downstream 02 sensor (after the cat). I located the sensor but don't know how to get to the connector. All the videos I watched had the connector just running along the exhaust frame. My car has it up under a metal plate that I guess I have to remove(pain in the ass). Is this how I get to it?? I wanna be sure before I jack the car up. Thanks for the help!

You have to remove the passenger side seat. The connector is under the carpet.

Thanks for the response. This sounds like alot more work than I expected. I can take the seat out easy enough, but is there alot more steps after that or is it a pretty easy installation? I'm trying to save money by doing it myself. I'm a poor college student!!

Once you get the seat out and the carpet up, you understand what you have to do to remove the O2 sensor.
I can't remember if you have to unbolt the heat shield on that one and drop it down. I work on so many cars everyday, I can't remember my first name..

I think being you live in a state that salts their roads you may want to take this one in. If you are broke you likely do not have the proper tools to get a frozen sensor out. A lot of times with a salted car I end up having to weld in a new threaded bung because the threads pull out when trying to remove the O2. I'm guessing you don't have a welder.
Wanted to warn you ahead of time what you might be up against. I live in WI so I get to see the evils of salt.
