Walker Products 350-34101 center oxygen sensor for the 2003-2005 Honda Civic 4-cylinder 1.3L and other vehicles measures the oxygen in the exhaust gas. This Walker Products oxygen sensor is a 4-wire narrow-band unit made for its fitment position, so it returns the feedback the ECU expects.
- Reports oxygen levels so the air-fuel mixture can be fine-tuned for combustion efficiency
- Electrodes made of a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and exhaust particulates
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 350-34101 oxygen sensor
- Fits: 2003-2005 Honda Civic 4-cylinder 1.3L and other vehicles
- Position: Center, upstream, downstream
- Condition: New
A failing sensor can show up as rough running, higher fuel use or a lit check engine light (MIL). A vacuum leak can cause similar rough running, so these signs alone don't prove the sensor is at fault. With the engine off and cool, the sensor, wiring harness and connector can be inspected for physical damage.
Fits
It is a direct-fit oxygen sensor for the 2005-2006 Honda CR-V 4-cylinder 2.4L and the 2003-2011 Honda Element 4-cylinder 2.4L, as well as the Civic above. If your car isn't named here, look it up by year and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is this the right oxygen sensor for a 2003-2005 Honda Civic 4-cylinder 1.3L?
Yes. Walker Products 350-34101 is listed for the 2003-2005 Honda Civic 4-cylinder 1.3L, and this listing is one sensor.
What thread size does the Walker Products 350-34101 sensor have?
Walker Products 350-34101 has an M18 - 1.5 thread and a 4-wire design.
Is this a narrow-band or wideband oxygen sensor?
Narrow-band. This oxygen sensor is a 4-wire narrow-band unit with electrodes made of a gas-permeable platinum layer.
Could a check engine light mean this oxygen sensor is wearing out?
It can. Rough running, higher fuel use or a lit check engine light can go with a failing sensor, and a shop can scan the codes to find the cause.
Does this listing include more than one oxygen sensor?
No. This listing is one oxygen sensor, and the fitment calls for one per vehicle.
