Bosch 16349 oxygen sensor for the 2013-2021 Chevrolet Trax 4-cylinder 1.4L and other vehicles measures the air-fuel ratio in the exhaust and reports it to the ECU. This Bosch premium oxygen sensor is a heated, narrow-band switching-type unit for the downstream position, and it helps the ECU keep combustion stable and emissions down.
A lit check engine light, a rough idle or poor fuel economy can mean the sensor is worn. An exhaust leak, a damaged connector or a misfire can be behind those signs too, so track down the cause before you buy a new sensor.
It fits the 2013-2021 Chevrolet Trax 4-cylinder 1.4L and the 2013-2021 Buick Encore 4-cylinder 1.4L, and it is also a 2010-2011 Saab 9-5 oxygen sensor for the V6 2.8L. This listing is one downstream sensor, and the 2013-2021 Chevrolet Trax 4-cylinder 1.4L takes one, as does each of the other cars.
