Walker Products 250-54038 oxygen sensor for the 2013-2017 Honda Accord 4-cylinder 2.4L and other vehicles measures the oxygen in the exhaust gas. This Walker Products oxygen sensor is an upstream, 4-wire wide-band air-fuel ratio sensor that sends the engine computer the feedback it needs.
- Measures oxygen levels in the exhaust to help fine-tune the air-fuel mixture and fuel economy
- Electrodes made of a gas-permeable platinum layer
- Monitors exhaust gases to help reduce pollutants
- Wide-band design that monitors the air-fuel ratio for combustion efficiency
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust
Quick facts
- Part: Walker Products 250-54038 oxygen sensor
- Fits: 2013-2017 Honda Accord 4-cylinder 2.4L and other vehicles
- Position: Upstream
- Condition: New
Rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light can mean this sensor is worn, though a damaged wiring harness or connector can be behind the same signs, so look both over for physical damage.
Fits
Besides the Accord, it fits the 2012-2015 Honda Civic 4-cylinder 2.4L and the 2014 Civic 4-cylinder 1.5L. It is also a Honda CR-V oxygen sensor for the 2012-2019 model years with the 4-cylinder 2.4L. If your car is not one of these, the "Vehicles it fits" section is where you can look up your year, model and engine. This listing is one sensor, and a 2013-2017 Honda Accord 4-cylinder 2.4L takes one.

Frequently Asked Questions
Is this the right Honda Accord oxygen sensor for a 2013-2017 model with the 4-cylinder 2.4L engine?
Yes. Walker Products 250-54038 is an upstream sensor for the 2013-2017 Honda Accord 4-cylinder 2.4L, and the Accord takes one. For other cars, use the "Vehicles it fits" section.
Is this a Honda Civic oxygen sensor for the 2012-2015 4-cylinder 2.4L or the 2014 4-cylinder 1.5L?
Yes. Walker Products 250-54038 fits the 2012-2015 Honda Civic 4-cylinder 2.4L and the 2014 Civic 4-cylinder 1.5L, in the upstream position.
What type of sensor is this 4-wire wide-band oxygen sensor?
This oxygen sensor is a wide-band air-fuel ratio sensor. It determines the oxygen content of the exhaust gas and monitors the air-fuel ratio for combustion efficiency.
What signs can point to a worn upstream oxygen sensor?
Poor engine running, higher fuel use, more exhaust emissions or a lit malfunction indicator light can be signs. Newer vehicles store fault codes, which a shop can read.
Does the coating on this oxygen sensor protect the electrodes?
Yes. The coating on this oxygen sensor prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases.
