I have tryed to look for this in the forms but had no luck. Can anybody tell were in the heck I would find my O2 censor for 02 tl type S. Im trying to replace it but I dont know were to find it. Thanks for the help!

 

Follow the exhaust pipe down from the engine- the thing with the wire going to it would be the sensor

 

u need to be under the car first off.. then u should see 2 big sensors sticking out of the exhaust pipe

 

Near the oil pan. Find the green wire connected to the collector pipe. That's the primary O2 sensor.

Secondary O2 sensor is located by the catalytic converter, and has a yellow wire.

 

Thanks for the help!!! Got it done. Now I need to change the Knock censor. Can I do this my self or should I have a professional do this job? and if I can do it my self howdo I get to it to change it? Thanks Again!!!
