Celica Forums General Discussion General O2 Sensors

Can anyone help me find where the O2 sensors make their connection?
I need to test to check for any failure.

Also, in California, can anyone replace a Cat converter, or do I have to go to Toyota to replace?

Thanks!

^^ the car has 2 O2 sensors i think. jack up the car, look for the exhaust piping in the front close to the engine. two wires go in exhaust piping somewhere below the the front seats.
any muffler shop can change a cat

I know where they go into the pipe!
I need to know where the other connection is!

i know give awhile to find the stuff on computer i have the same problem

i think Isaac gave me this...
The O2 sensor comes up through the floor panel on the passenger side.

1) Make sure car is OFF.
2) Remove passenger side seat.
3) Remove kick panel (under the glove box)
4) Remove carpet fasteners
5) Remove carpet
6) Jack car up
7) follow the o2 sensor wiring you need to replace up to where it goes in the car.
8) wires go through a grommet
9) Push grommet through and replace o2 sensor.

its a lot different from any crapy civic
