posted 3 times now and forget to say FRONT SENSOR> right, not the Rear 02 sensor....? and still no engine stated.! nor country, (USA calif, usa FED, or canada) strike three you are out. sorry. there are 3 engines, based on all 3 engine schematics, my wild guess is 7AFE engine. (the brown wire clue) 1,8L 4AFE (1.6L) or 1ZZFE engine, DOHC 1.8L
There are a total of 4 02 sensors on your vehicle. Each side of the engine has 2 02 sensors. 1 sensor is located before the catalytic converter, and 1 sensor after the converter for each exhaust. You will have to remove the lower plastic covers under the car to access where the sensors are located. They are located in the exhaust forward of the transmission. You will need either a 22mm or 24mm open end wrench, or preferably an oxygen sensor removal tool which can be purchased from an automotive store or even Sears. In addition you may need a 3/8 ratchet.The sensors can be pricey and I recommend staying with Bosch brand if possible. It is best to remove the sensors when the exhaust is cold.
you need to borrow the oxygen sensor wrench from autozone or whereever you bought the sensor.
