Is the oxygen sensor and MAF sensor the same?
The oxygen sensor is in the exhaust. It senses unburned oxygen to tell the computer if combustion is complete. The mass airflow sensor is in front of the intake. It measures the volume of incoming air to supply the right amount of fuel There are two O2 sensors in the exhaust system (4cyl). One is the a/f sensor the second is the downstream or heated sensor. The first measures air/fuel metering; the second measures the efficiency of the catalytic converter. The MAF sensor measures the Mass Air Flow, and yes it is at the front of the intake between the engine air filter and the throttle plate.
