Ok im no mechanic so please bare with me.

I have a 2002 camry se 3.0 6cyl. Engine light is on.. I bought a good hand held scanner by Innova its the 3150b.

I followed the directions and came up with a code of P1135 AF Heater circuit sensor malfunction, bank 1 sensor 1. Is this the same as the o2 sensor ? and if so where is bank 1 sensor 1 on this car.. I cant affford Toyota parts so from researching I read that Denso parts are good replacement parts.. I just have no idea which one I need to buy. Autozone has a bunch of these on there site. I want to sell the car so I dont want to spend allot of money for top end parts, I just want to fix it so I can sell it without feeling like I ripped off the buyer. Also what does upstream and downstream mean?
