Walker Products 250-241177 oxygen sensor for the 2015-2017 Toyota Yaris 4-cylinder 1.5L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. This downstream Walker Products oxygen sensor is a direct-fit, narrow-band unit.

• Electrodes coated with a gas-permeable platinum layer
• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
• Determines the oxygen content of the exhaust gas and monitors the air-fuel ratio for combustion efficiency
• Monitors exhaust gases and helps reduce pollutants
• Measures oxygen levels so the air-fuel mixture can be fine-tuned, which helps fuel economy
