What does it mean when a code for an O2 sensor on your converter says lean O2 sensor?

They switch back and forth (electrical, over and under the median) constantly monitoring air in exhaust and adjust run time on your injectors to compenste. but you should have about 3. You are running leaner on that bank than it can correct, or your sensor has become lazy (slow switching)and needs replaced. You need someone with an advanced scanner that can not only test your sensors, but check fuel trims to determine what you need. A new sensor is only about 40.00, but some are hard to replace depending on location.

Where is the 02 sensor located on 2001 Chevrolet Malibu?
All oxygen sensors are located in the exhaust system. Some have one in the manifold, some have one before the catalytic converter. Then others have one before and one after the converter. It requires a special socket to remove and replace it. Just because your code says oxygen sensor, does not mean it is bad. A vacuum leak can give a code that the sensor is reading lean.
