If you are referring to the mass air flow sensor, its part of the tunnel between the air filter and the throttle body. It measures the airflow based on the amount of cooling that the air flowing over two heated wires, based upon a programmed set of comparisons inside the computer, then the computer reacts by changing fuel mix...It can be cleaned with carb cleaner and a Q-tip on the two wire elements (carefully)

My inside temp led didplay always shows 50 degrees for my 2002 trailblazer so the Ac won't blow really cold air

If you mean the temperature display on the rearview mirror, you need to replace the outside temperature sensor. It is located under the hood, on the radiator support on the top near center.

Throttle Problem

Well 2002 will be port injected,so the throttle body only adjust air flow.Try cleaning Mass Air Flow Sensor and replacing your fuel filter.Make sure that your air filter is clean.If you havn't had a tune up in 100,000 miles then it's time.It could be the TPS ,but would try the others first.Well hope this helps,and good luck.

Location of oxygen sensors

I think there is more than two. Either way, they are located in the exhaust system. The pre-cat sensors are in the head pipes, just below the exhaust manifold, and then there will be one right behind the catalytic converter. You will need a 7/8 inch wrench or possibly a special O2 socket.
