Oxygen Sensors: same front and rear?

buda315 · 01-16-2013, 07:02 PM

Are the two pre-cat 02 sensors on the front and rear the same?

My mechanic was supposed to have replaced the bank 1 sensor on my 2006 V6, but he did the front instead. My understanding is that he had the wrong bank.

Bank 1 being at the firewall and Bank 2 near the radiator.

Anyways, I plan on replacing the "correct" rear sensor along w/ the spark plugs.

Does anyone know if both front and rear O2 sensors are the same part?

Yes if I remember right. Here are the part #'s

Front 39210-3C100 (pre cats)
Rear R 39210-3C200

L 39210-3C400

Hope this helps.
