Walker Products 350-31023 oxygen sensor for the 1984-1985 Honda Accord 4-cylinder 1.8L, the 1986-1989 Accord 4-cylinder 2.0L and other vehicles measures the oxygen content of the exhaust gas. This Walker Products oxygen sensor is a narrow-band, direct-fit unit for the upstream position.
- Oxygen sensor monitors exhaust gases and helps reduce pollutants
- Air-fuel ratio monitoring from the exhaust oxygen content, for combustion efficiency
- Coating protects the electrode surfaces from combustion residue and particulates in the exhaust gas
- Electrodes made of a gas-permeable platinum layer
- Oxygen readings help fine-tune the air-fuel mixture and support fuel economy
Quick facts
- Part: Walker Products 350-31023 oxygen sensor
- Fits: the 1984-1985 Honda Accord 4-cylinder 1.8L, the 1986-1989 Accord 4-cylinder 2.0L and other vehicles
- Position: Upstream
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. These signs alone do not prove the sensor is the problem, since a vacuum leak can cause some of them too. Also look over the wiring harness and connector for physical damage.
Fits
Besides those Accords, this oxygen sensor fits the 1988-1991 Honda Civic 4-cylinder 1.5L or 1.6L and the 1986-1995 Suzuki Samurai 4-cylinder 1.3L. If your car is not named here, run its year and engine through the "Vehicles it fits" section before ordering. This listing is one upstream sensor, and the fitment calls for one per engine.

Frequently Asked Questions
Will this Honda Accord oxygen sensor fit a 1986-1989 Honda Accord 4-cylinder 2.0L?
Yes. Walker Products 350-31023 is listed for the 1986-1989 Honda Accord 4-cylinder 2.0L. For other years and engines, use the "Vehicles it fits" section.
Is Walker Products 350-31023 a narrow-band or wideband oxygen sensor?
Narrow-band. Walker Products 350-31023 is a narrow-band unit made for the upstream position, with an M18 - 1.5 thread.
What can a failing upstream oxygen sensor cause?
It can show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light. A shop can read the stored fault codes to see whether the sensor is involved.
What does the coating on this oxygen sensor protect?
The coating guards the electrode surfaces against contamination and erosion from combustion residue and particulates in the exhaust gas. The electrodes use a gas-permeable platinum layer.
Will the 350-31023 send the ECU the feedback it expects?
Yes. Each Walker Products part number is made for its specific application and fitment position, and it gives the diagnostic system feedback the ECU requires.
