Walker Products 350-34606 oxygen sensor for the 2003-2008 Toyota Corolla 4-cylinder 1.8L and other vehicles measures the oxygen content of the exhaust gas. It is a narrow-band sensor with four wires.
- Monitors the air-fuel ratio so the ECU can fine-tune the mixture for combustion efficiency
- Electrodes made of a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Monitors exhaust gases to help reduce pollutants
- Made for its specific application and fitment position, with the diagnostic feedback the ECU requires
Quick facts
- Part: Walker Products 350-34606 oxygen sensor
- Fits: 2003-2008 Toyota Corolla 4-cylinder 1.8L and other vehicles
- Position: Upstream, downstream
- Condition: New
A failing oxygen sensor can make the engine run poorly, raise fuel consumption or exhaust emissions, or turn on the malfunction indicator light. An exhaust leak, a damaged wiring harness or connector, or a fuel-system fault can be behind the same signs, so find the cause before you buy a sensor. With the engine off and cool, look over the sensor, harness and connector for physical damage.
