Walker Products 350-34126 oxygen sensor for the 1990-1997 Honda Accord 4-cylinder 2.2L and other vehicles measures the oxygen in the exhaust gas. This Walker Products oxygen sensor is the upstream, narrow-band type with four wires.
- Coating guards the electrode surfaces against contamination and erosion from combustion residue and particulates in the exhaust
- Electrodes made with a gas-permeable platinum layer
- Monitors exhaust gases and the air-fuel ratio to track combustion efficiency and help keep emissions down
- Measures oxygen levels to help fine-tune the air-fuel mixture for fuel economy
- Made for its specific application and fitment position, with the diagnostic feedback the ECU requires
Quick facts
- Part: Walker Products 350-34126 oxygen sensor
- Fits: 1990-1997 Honda Accord 4-cylinder 2.2L and other vehicles
- Position: Upstream
- Condition: New
Rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light can come from a failing sensor, but they also turn up with unrelated problems. With the engine off and cool, look over the sensor, its wiring harness and the connector for physical damage; damage there can shorten the sensor's life.
Fits
This oxygen sensor also fits the 1999-2000 Honda Civic 4-cylinder 1.6L and the 1997-2001 Honda CR-V 4-cylinder 2.0L. A single sensor goes on each of these cars, and this listing is one sensor. If your car is not named here, find your own year and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Will this oxygen sensor fit a 1990-1997 Honda Accord 4-cylinder 2.2L?
Yes. Walker Products 350-34126 is a direct-fit upstream oxygen sensor for the 1990-1997 Honda Accord 4-cylinder 2.2L, and that Accord takes one sensor.
Is the Walker Products 350-34126 a narrow-band sensor, and how many wires does it have?
Yes. Walker Products 350-34126 is a narrow-band oxygen sensor with four wires, made for the upstream position.
What are the electrodes on this oxygen sensor made of?
The electrodes are made with a gas-permeable platinum layer. A coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust.
What symptoms can come with a failing upstream oxygen sensor?
Rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light can come with a failing sensor. Newer cars may also store a related fault code in the ECU.
How does this oxygen sensor work with the engine computer?
This sensor measures the oxygen in the exhaust gas to track the air-fuel ratio. It is made for its specific application and position to give the ECU the diagnostic feedback it requires.
