My car is a base-model FWD with about 80,000 miles on it. I had the computer scanned at O'Reillys. It was a P1071 "Running Lean" Bank 1 code. I cleaned the MAF sensor and checked for vacuum leaks. I reset the CEL light when I cleaned the MAF by disconnecting the battery. 85 miles later, the CEL light came back on. I took it to the local mechanic and he said it needs a new upstream o2 sensor (based on their diagnosis). They wanted $245 for the sensor. I thought that was a bit STEEP!

Anyways, my question is, is an Air Fuel Sensor the same thing as an o2 sensor? Also, the mechanic said my Vibe requires a heated o2 sensor, which the Denso product is heated.

Thanks
