Yes, to keep the fuel mixture correct. Fuel mixture helps your vehicle get power when it needs it and controls the MPG. Also, depending on your engine, there are 4 O2 sensors, 2 before the converter and 2 after the converter.
How many oxygen sensors are there for a 2001 Chevy Tahoe 5.3L
4 oxygen sensors. 2 upstream of the catilitic converter and 2 down stream of the converter. That is for the exhaust system.
There are 4. Two upstream (bank1) two downstream (bank2).
I think it has 3 But it may have 4 on that year. Don't remember SORRY.
A 1999 Chevy Tahoe typically has two oxygen sensors. One is located before the catalytic converter (upstream sensor), and the other is located after the catalytic converter (downstream sensor). These sensors monitor the oxygen levels in the exhaust gases to help the engine control module adjust the air-fuel mixture for optimal combustion efficiency and reduced emissions.
