Walker Products 350-34122 oxygen sensor for the 2003-2007 Honda Accord 4-cylinder 2.4L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. This Walker Products oxygen sensor is a narrow-band unit for the downstream position.
- Measures oxygen levels to help fine-tune the air-fuel mixture and support fuel economy
- Coating protects the electrode surfaces from combustion residue and particulates in the exhaust gas
- Electrodes made of a gas-permeable platinum layer
- Monitors exhaust gases to help reduce pollutants
- Made for its specific application and fitment position, with the diagnostic feedback the ECU needs
Quick facts
- Part: Walker Products 350-34122 oxygen sensor
- Fits: 2003-2007 Honda Accord 4-cylinder 2.4L and other vehicles
- Position: Downstream
- Condition: New
Rough running, higher fuel consumption, more exhaust emissions or a check engine light can mean a failing sensor. A damaged wiring harness or connector, or an unrelated engine fault, can be behind them too, so find the cause before buying a sensor.
Fits
