Walker Products 350-34189 oxygen sensor for the 1998-2000 Honda Civic 4-cylinder 1.6L and other vehicles measures the oxygen level in the exhaust gas. It is a 4-wire, narrow-band, direct-fit sensor for the downstream position and sends the ECU the feedback it needs.
- Monitors exhaust gases to help reduce pollutants
- Electrodes made of a gas-permeable platinum layer
- Determines the oxygen content of the exhaust gas, monitoring the air-fuel ratio for combustion efficiency
- Measures oxygen levels to fine-tune the air-fuel mixture and support fuel economy
- Coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gas
Quick facts
- Part: Walker Products 350-34189 oxygen sensor
- Fits: 1998-2000 Honda Civic 4-cylinder 1.6L and other vehicles
- Position: Downstream
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption or a lit malfunction indicator light, though other faults produce those signs too. With the engine off and cool, look over the sensor, its wiring harness and the connector for physical damage; a shop can test the signal itself.
Fits
This sensor is listed for a wide range of Honda and Acura models, led by the 1998-2000 Honda Civic 4-cylinder 1.6L, the 1997-2001 Honda CR-V 4-cylinder 2.0L and the 1996-2001 Acura Integra 4-cylinder 1.8L. Driving something else? Look up your own year and engine in the "Vehicles it fits" section. This listing is one sensor, and a car needs one in this downstream spot.

Frequently Asked Questions
Is Walker Products 350-34189 an oxygen sensor for the 1998-2000 Honda Civic 4-cylinder 1.6L?
Yes. Walker Products 350-34189 is a direct-fit downstream oxygen sensor for the 1998-2000 Honda Civic 4-cylinder 1.6L. For other Honda and Acura models, use the "Vehicles it fits" section.
Is this an oxygen sensor for the 1997-2001 Honda CR-V 4-cylinder 2.0L?
Yes. This downstream sensor is listed for the 1997-2001 Honda CR-V 4-cylinder 2.0L, and that engine takes one.
How many wires does the Walker Products 350-34189 oxygen sensor have?
Four. Walker Products 350-34189 is a 4-wire, narrow-band, direct-fit sensor for the downstream position.
What can a failing downstream oxygen sensor cause?
Signs can include rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. These can have other causes, so a shop can read the stored codes.
What does the platinum layer on this oxygen sensor do?
The electrodes are made of a gas-permeable platinum layer. The coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gas.
