    Bosch 15914 oxygen sensor for the 2004-2009 Mazda 3 4-cylinder 2.0L and the 2006-2009 3 4-cylinder 2.3L measures exhaust oxygen from the downstream position and sends air-fuel-ratio readings to the ECU. This Bosch O2 sensor is a heated, narrow-band type that helps the ECU manage combustion and emissions.

    • Switching-type sensor that gives the ECU air-fuel-ratio feedback
    • Metal housing, integrated heater element and TSP coating resist vibration, corrosion and contamination
    • Built to withstand exhaust streams up to 1,880°F
    • Reaches operating temperature in under 10 seconds for quick closed-loop control

    Quick facts

    A check engine light, lower fuel economy or rough running can mean the oxygen sensor is worn. An exhaust leak, a damaged wiring connector, the upstream sensor or a tired catalytic converter can be behind the same signs, so find the cause before buying.
