Description

Bosch 18188 oxygen sensor for the 2014-2018 Mazda 3 4-cylinder 2.0L or 2.5L and other vehicles measures the air-fuel ratio in the exhaust and reports it to the ECU. That feedback supports stable combustion control and helps reduce emissions.

Narrow-band switching sensor that sends air-fuel-ratio readings to the ECU
Reaches operating temperature in under 10 seconds for quick closed-loop control
Integrated heater element, built to withstand exhaust streams up to 1,880°F
Metal housing with TSP coating to resist vibration, corrosion and contamination

Quick facts

Condition: New

A lit check engine light, poorer fuel economy or a failed emissions test can point to a worn oxygen sensor. Before you replace it, rule out exhaust leaks and damaged wiring, since either can set off the same warning. This listing is one sensor, and each listed engine takes one in the downstream position.

It is listed for a wide range of Mazda models, including the 2014-2018 Mazda 3 4-cylinder 2.0L or 2.5L, the 2014-2021 Mazda 6 4-cylinder 2.5L and the 2019-2025 Mazda CX-5 4-cylinder 2.5L. If your car is not named here, open the "Vehicles it fits" section to check your exact model and engine.
