    Just got a PO135 OBD2 code from check engine light. O2 heater circuit malfunction (bank 1, sensor 1). Its a 2.7L engine. Just to verify that would be the sensor on the exhaust manifold, correct? And when i go to buy one from the dealer, what is the proper name of said o2 sensor? Thank you for any help.

    Nice! A friend of mine had 640k miles on his 2.7 when he let it go!

    I wouldnt buy it from the dealer unless you have deep pockets. Go to Denso's web site and look up the part number. Then do a search on ebay for that Denso part number and look for a good deal there. You will save at least 60 bucks that way. But make sure you buy Denso, since some of the other brands can cause problems.
