Bosch Oxygen Sensor P/N:13644
Bosch 18102 oxygen sensor for the 2012-2013 Mazda 3 4-cylinder 2.0L and other vehicles reads the exhaust air-fuel ratio for the engine computer. This upstream Bosch O2 sensor is a wideband type that gives the ECU more detail than a switching sensor.
A rough idle, a check engine light or poorer fuel economy can mean the sensor is worn. These signs alone do not prove the sensor is the problem, since a vacuum leak can also skew the air-fuel reading. This listing is a single sensor, and the engine takes one in the upstream position.
This sensor is a direct-fit replacement for the 2012-2013 Mazda 3 4-cylinder 2.0L and the 2012-2013 Mazda 3 Sport 4-cylinder 2.0L.
