Walker Products 250-241133 oxygen sensor for the 2013-2015 Chevrolet Malibu 4-cylinder 2.0L or 2.5L, the 2016-2019 Malibu 4-cylinder 1.8L and other vehicles is a narrow-band, 4-wire sensor that reads the oxygen content of the exhaust gas.
- Oxygen readings let the air-fuel mixture be fine-tuned, which supports fuel economy
- Monitors exhaust gases to help reduce pollutants
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Electrodes made of a gas-permeable platinum layer
- Built for its specific application and fitment position, with the diagnostic feedback the ECU requires
Quick facts
- Part: Walker Products 250-241133 oxygen sensor
- Fits: the 2013-2015 Chevrolet Malibu 4-cylinder 2.0L or 2.5L, the 2016-2019 Malibu 4-cylinder 1.8L and other vehicles
- Position: Upstream, upstream left, upstream right
- Condition: New
A failing sensor can show up as rough running, higher fuel use or a lit malfunction indicator light. Before you replace the sensor, rule out a damaged wiring harness or connector, since either can produce these symptoms too; look both over for physical damage.
Fits
This direct-fit oxygen sensor is listed for a wide range of Chevrolet, GMC, Buick and Cadillac models, including the 2017-2021 GMC Acadia 4-cylinder 2.5L and the 2014-2019 Chevy Impala 4-cylinder 2.5L. Open the "Vehicles it fits" section to check your exact model and engine.

Frequently Asked Questions
Is this the right Chevy Malibu oxygen sensor for a 2016-2019 Malibu 4-cylinder 1.8L?
Yes. Walker Products 250-241133 is listed for the 2016-2019 Chevrolet Malibu 4-cylinder 1.8L, and also for the 2013-2015 Malibu 4-cylinder 2.0L or 2.5L.
Is this Walker Products oxygen sensor narrow-band or wideband?
Walker Products 250-241133 is a narrow-band oxygen sensor with four wires. It is listed for upstream positions, including upstream left and upstream right.
How does the 250-241133 oxygen sensor help keep the air-fuel mixture in check?
It determines the oxygen content of the exhaust gas, and those readings let the air-fuel mixture be fine-tuned. Monitoring the exhaust also helps reduce pollutants.
What can a failing upstream oxygen sensor cause?
Rough running, higher fuel consumption or a malfunction indicator light can come with a failing sensor. Newer vehicles may also store fault codes in the ECU that relate to the sensor.
What does the coating on this oxygen sensor's electrodes do?
The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases. The electrodes are made of a gas-permeable platinum layer.
