What Oxygen Sensor does for your vehicle.

Reducing harmful emissions that come from your car or truck depends on the quality and performance of the parts you use. The fuel-injection system on your Mazda Protege5 is runs on signals sent by your ECU which relies on input from the oxygen sensors. Your Mazda Protege5 oxygen sensors sit in the exhaust manifold, exhaust pipes, and catalytic converter and analyze the quality of the exhaust gases to determine how well your fuel delivery and emissions reduction parts are working. When oxygen sensors fail your car will not get the best fuel economy or produce enough horsepower, and it will likely be emitting an excess of hazardous exhaust.

You've tried the rest, now try the best.
