NGK O2 24460 sensor for the 2012-2017 Mazda 5 4-cylinder 2.5L and other vehicles measures the oxygen left in the exhaust and reports it to the ECU. That closed-loop feedback helps the ECU control the air-fuel ratio and alerts OBDII systems to possible fuel delivery or catalytic converter efficiency problems.
A check engine light, a rough idle or poor mileage can mean the sensor is worn, but they do not prove it; a vacuum leak is another common source. This listing is one sensor, and the engine takes one.
This sensor fits the 2011-2013 Mazda 3 4-cylinder 2.5L, the 2011-2013 Mazda 3 Sport 4-cylinder 2.5L and the 2012-2017 Mazda 5 4-cylinder 2.5L.
