P1071 Code

03-24-2005, 09:12 PM
I have a 2000 Avalon that has a P1071 code which has given me a to lean bank one code. I have asked three dealers and have received three different answers as to where is the sensor for bank one. There are two a/f sensors, one in the front of the motor, one in the rear, and a 02 in front of the conveter. But which one is bank one? Where can I get a schematic that would tell me the correct location. It is a V6.

Here's a diagram showing you the location/names of the different sensors.

Try cleaning the MAF meter near the air cleaner housing.
