Walker Products 350-34403 oxygen sensor for the 1990-1993 Honda Accord 4-cylinder 2.2L and other vehicles measures the oxygen content of the exhaust gas to show how efficiently the engine burns fuel. This Walker Products oxygen sensor is made for its specific application and fit position, and gives the ECU the diagnostic feedback it requires.
- Narrow-band design with 4 wires
- Monitors the oxygen content of the exhaust gas to track the air-fuel ratio
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Oxygen readings help fine-tune the air-fuel mixture for normal fuel economy and fewer exhaust pollutants
- Electrodes are coated with a gas-permeable platinum layer
Quick facts
- Part: Walker Products 350-34403 oxygen sensor
- Fits: 1990-1993 Honda Accord 4-cylinder 2.2L and other vehicles
- Position: upstream, downstream
- Condition: New
A failing sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light. Those signs alone do not prove the sensor is at fault, because an exhaust leak can cause some of them too. Look over the sensor's wiring harness and connector for physical damage.
Fits
It is a direct-fit replacement for the 1990-1993 Honda Accord 4-cylinder 2.2L, the 1992-1993 Honda Prelude 4-cylinder 2.2L and the 2003 Acura EL 4-cylinder 1.7L. This listing is one sensor, and the 1990-1993 Honda Accord 4-cylinder 2.2L takes one.

Frequently Asked Questions
Does this Honda Accord oxygen sensor fit the 1990-1993 Accord 4-cylinder 2.2L?
Yes. Walker Products 350-34403 is a direct-fit sensor for the 1990-1993 Honda Accord 4-cylinder 2.2L, and that engine takes one.
Is there a Honda Prelude oxygen sensor here for the 1992-1993 Prelude 4-cylinder 2.2L?
Yes. Walker Products 350-34403 fits the 1992-1993 Honda Prelude 4-cylinder 2.2L, and that car takes one.
Is this oxygen sensor narrow-band or wideband?
It is narrow-band. This sensor has 4 wires, and its electrodes are coated with a gas-permeable platinum layer.
What happens when a narrow-band oxygen sensor like this one wears out?
The engine can run poorly, use more fuel, put out more exhaust emissions or turn on the malfunction indicator light. Newer vehicles may also store a fault code in the ECU.
How does the coating on this oxygen sensor help?
The coating on the electrode surfaces keeps combustion residue and particulates in the exhaust from contaminating or eroding them.
