All oxygen sensors are located in the exhaust system.depending on the model you have one or as many as 4 ,more in some cases,find out which(up stream or down stream,right bank or left) then follow the exhaust manifold,the one befor catalytic convertor is up stream and after is downstream.

It also has to reach normal operating temp of 195 degrees.

Not passing smog check


bank 1 is pass/side exhaustpipe/converter bank 2 is on the driverside,this car has two converters, so you have 4 oxygen sensors, one before and one after the converter on each side, so bank 1 sensor1 is pass/side before the converter, bank 1 sensor 2 is pass/side after the converter, then bank 2 sensor1 is driverside before the converter, before means starting at motor, then bank 2 sensor 2 is driverside after the converter, heres a diagram to help, i hope this is helpful.a9203dd.jpg33c9cf6.jpg
