Walker Products 250-241208 oxygen sensor for the 2017-2020 Honda Accord 4-cylinder 2.0L and other vehicles measures the oxygen content of the exhaust gas. The Walker Products oxygen sensor is a 4-wire, narrow-band, direct-fit design made for its specific application and fitment position.
- Electrodes with a gas-permeable platinum layer
- Air-fuel ratio monitoring for combustion efficiency
- Exhaust gas monitoring that helps reduce pollutants
- Oxygen readings that help fine-tune the air-fuel mixture and support fuel economy
- Coating that protects the electrode surfaces from contamination and erosion by combustion residue and particulates
Quick facts
- Part: Walker Products 250-241208 oxygen sensor
- Fits: 2017-2020 Honda Accord 4-cylinder 2.0L and other vehicles
- Position: Downstream
- Condition: New
A failing sensor can show up as a rough-running engine, higher fuel use, more exhaust emissions or a lit malfunction indicator light. With the engine off and cool, look the sensor, wiring harness and connector over for physical damage. Those parts, or the spark plugs, can be behind these symptoms too, so find the cause before buying a sensor.
Fits
It is also an oxygen sensor for the 2016-2021 Honda Civic 4-cylinder 1.5L, the 2017-2023 Honda CR-V 4-cylinder 1.5L and the 2020-2022 CR-V 4-cylinder 2.0L, and the fit extends to many other vehicles. This listing is one sensor, and the fitment calls for one downstream sensor per vehicle.

Frequently Asked Questions
Is this an oxygen sensor for the 2017-2020 Honda Accord 4-cylinder 2.0L?
Yes, Walker Products 250-241208 fits the 2017-2020 Honda Accord 4-cylinder 2.0L at the downstream position. For another car, pick your vehicle in the "Vehicles it fits" section.
Is this Walker Products oxygen sensor narrow-band or wideband?
It is narrow-band: Walker Products 250-241208 is a 4-wire, direct-fit narrow-band design.
What does the coating on this oxygen sensor protect against?
The coating guards the electrode surfaces against contamination and erosion from combustion residue and particulates in the exhaust gas. The electrodes have a gas-permeable platinum layer.
What can a failing downstream oxygen sensor look like?
It can show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light. A shop can read stored fault codes to narrow it down.
Does a sensor like this affect fuel economy and emissions?
It can help. The sensor measures oxygen levels so the air-fuel mixture can be fine-tuned, and it monitors exhaust gases to help reduce pollutants.
