Walker Products 250-25137 oxygen sensor for the 2016-2021 Honda Civic 4-cylinder 1.5L, the 2016-2023 Civic 4-cylinder 2.0L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. This Walker Products oxygen sensor is engineered as an Original Equipment Manufacturers replacement, and it sends the ECU the diagnostic feedback it requires.
- 5-W wide-band design
- Electrodes made of a gas-permeable platinum layer
- Coating that prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases
- Monitors exhaust gases and reduces pollutants
- Measures oxygen levels to fine-tune the air-fuel mixture for fuel economy
- Manufactured for its specific application and fitment position
Quick facts
- Part: Walker Products 250-25137 oxygen sensor
- Fits: 2016-2021 Honda Civic 4-cylinder 1.5L, the 2016-2023 Civic 4-cylinder 2.0L and other vehicles
- Position: Upstream, upstream left, upstream right, upstream rear, upstream front
- Condition: New
A failing sensor can make the engine run poorly, raise fuel consumption or turn on the malfunction indicator light, and newer vehicles may store sensor-related fault codes in the ECU. Before you replace it, look over the wiring harness and connector for physical damage, since damage there can shorten a sensor's life and other faults can also set that light.
Fits
It is also an oxygen sensor for the 2017-2023 Honda CR-V 4-cylinder 1.5L, one of the top vehicles it fits. The listing holds one sensor, and the fitment calls for one per vehicle.

Frequently Asked Questions
Is this a Honda Civic oxygen sensor for a 2016-2023 Civic 4-cylinder 2.0L?
Yes. Walker Products 250-25137 fits the 2016-2023 Honda Civic 4-cylinder 2.0L and the 2016-2021 Civic 4-cylinder 1.5L. If your car is another Honda, look it up in the "Vehicles it fits" section.
Is this the right Honda Pilot oxygen sensor for a 2020-2022 Pilot V6 3.5L?
Yes. This sensor fits the 2020-2022 Honda Pilot V6 3.5L, and the listing is one sensor, which is the quantity the fitment gives for that vehicle.
What thread size does the Walker Products 250-25137 oxygen sensor have?
It is a threaded sensor with an M18 - 1.5 thread, and it is listed as a 5-W wide-band unit.
What signs can show this wide-band oxygen sensor is failing?
A failed sensor can show up as the engine running poorly, higher fuel consumption or an illuminated malfunction indicator light. Newer vehicles also store fault codes in the ECU, some tied to the sensor.
What does the coating on this oxygen sensor protect?
Walker Products 250-25137 has electrodes made of a gas-permeable platinum layer. Its coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases.
