Walker Products 350-34518 oxygen sensor for the 2000-2004 Volvo S40 4-cylinder 1.9L and other vehicles measures the oxygen in the exhaust gas. That reading shows how efficiently the engine burns fuel, and the sensor is made for its specific application and fitment position to give the ECU the diagnostic feedback it needs.
- Measures oxygen levels in the exhaust to help fine-tune the air-fuel mixture and support fuel economy
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Monitors exhaust gases to help reduce pollutants
- Electrodes made of a gas-permeable platinum layer
- Narrow-band sensor with four wires
Quick facts
- Part: Walker Products 350-34518 oxygen sensor
- Fits: 2000-2004 Volvo S40 4-cylinder 1.9L and other vehicles
- Position: Upstream
- Condition: New
A worn sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light, though damage to the sensor's wiring harness or connector can be behind the same signs, so look both over for physical damage first.
Fits
