Walker Products 350-34577 oxygen sensor for the 2006-2011 Honda Civic 4-cylinder 2.0L and other vehicles measures the oxygen in the exhaust gas to gauge combustion efficiency. This downstream sensor is a direct-fit, narrow-band unit with four wires.
- Monitors exhaust gases and reduces pollutants for a cleaner environment
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust
- Electrodes made of a gas-permeable platinum layer
- Measures oxygen levels so the air-fuel mixture can be fine-tuned, which helps fuel economy
- Made for its specific application and fitment position, with the diagnostic feedback the ECU needs
Quick facts
- Part: Walker Products 350-34577 oxygen sensor
- Fits: 2006-2011 Honda Civic 4-cylinder 2.0L and other vehicles
- Position: Downstream
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. An exhaust leak, a damaged wiring harness or a damaged connector can be behind the same signs, so find the cause before buying a sensor. A harness or connector in poor shape can also shorten a sensor's life.
Fits
It is listed for a wide range of Honda and Acura models, including the 2007-2008 Honda Fit 4-cylinder 1.5L and the 2018-2020 Honda City 4-cylinder 1.5L. The car takes one downstream sensor, and this listing is a single sensor.

Frequently Asked Questions
Is this the right oxygen sensor for a 2006-2011 Honda Civic 4-cylinder 2.0L?
Yes, Walker Products 350-34577 is listed for the 2006-2011 Honda Civic 4-cylinder 2.0L as a downstream sensor, and the car takes one.
Is this the downstream oxygen sensor for a 2007-2008 Honda Fit 4-cylinder 1.5L?
Yes, Walker Products 350-34577 is listed for the 2007-2008 Honda Fit 4-cylinder 1.5L, one per car. If your car is not named here, look it up in the "Vehicles it fits" section.
Is this Walker Products oxygen sensor narrow-band or wideband?
It is narrow-band. This downstream sensor has four wires and an M18 - 1.5 thread.
Can a bad downstream oxygen sensor turn on the check engine light?
Yes, it can. A failed sensor may also bring rough running, higher fuel use or more exhaust emissions, and a shop can read the stored fault codes to see which circuit is involved.
Does CTK-OSHO4015 interchange with Walker Products 350-34577?
Yes, CTK-OSHO4015 is listed as an interchange number for Walker Products 350-34577, a downstream narrow-band oxygen sensor.
