Oxygen sensors measure how rich or lean the gases are that exit the combustion chamber. If the exhaust gas is high, or lean, in oxygen content or low, rich, in oxygen content, the amount of fuel that the engine takes in is adjusted by the engine management computer to maintain the sufficient mixture that produces the lowest emission output possible from the catalytic convertor. The throttle position sensor (TPS) measures the changes in the throttle position and controls the RPMs of your engine. The ABS sensor is constantly monitoring and reporting the rotational speed of each tire and is a safety system that prevents your car from skidding or sliding when you apply pressure on the brakes. The mass airflow sensor measures the amount of air that enters the engine. If this sensor fails, the engine will provide more or less oxygen to the fuel feeding into your engine resulting in poor gas mileage and power.
