Mazda Oxygen Sensor 0 258 003 703 is positioned in the exhaust pipe, in the location where the oxygen content can be measured right before it leaves the cylinder. It is also known as O2 sensor, lambda probe, lambda sensor, lambda sond or EGO sensor. This instrument accurately checks the red-hot exhaust hundreds of times per minute with the goal of helping the emissions control system produce the least exhaust gases as possible. The chemical reaction that the sensor produces generates voltage, which then determines if the mixture is lean or rich and adjusts the amount of fuel entering the engine for balancing. If the sensor fails to execute its operation properly, the computer then would end up guessing the air and fuel ratio and consequently also fail to adjust fuel amount. The sensing ability of a Mazda oxygen sensor can be affected by altitude, air and engine temperature, barometric pressure, engine load and some other aspects.
