Can anyone help me ?!

I have 97 Maxima GLE.

My check engine light is on and I had it computer diagnosed.
I got error code: PO150 Bank 2 , Sensor 1.

Also my mileage now is 13 m/g in the city.

I was told it's one of the front O2 sensors probably on radiator side.

I would like to buy the sensor on eBay but I don't know which one do I need.

I know that there are 2 sensors in the front: one on the radiator side and one near firewall side.

Are two of those front sensors the same or they are different ???

Which of the two sensors do I need ? and where can I find it on eBay ?

I looked on ebay, all sensors they sell called just "Front" or "Back" and I dont see any "Radiator side" or "Firewall side" sensors.



Thanks for your help

check the stickies! without checking myself it sounds like you need one of the pre-cat sensors, of which there are two, both the same. $70 - $140 depending what and where.

I changed both front O2 sensors and knock sensor, gas and air filter.
Now I have much more power , especially on low rpm. Also the car doesn't shake any more when it stands with shifter on D. Day and nite difference !
