Walker Products 350-34557 oxygen sensor for the 2001-2005 Mazda Miata 4-cylinder 1.8L reads the oxygen content of the exhaust gas from the downstream position. It is a narrow-band, 4-wire sensor made for its specific application and fitment position.

• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
• Electrodes made of a gas-permeable platinum layer
• Measures oxygen levels to help fine-tune the air-fuel mixture and fuel economy
• Monitors exhaust gases to help reduce pollutants
• Supplies the diagnostic feedback the ECU needs from this position

Quick facts

• Part: Walker Products 350-34557 oxygen sensor

Rough running, higher fuel consumption or a lit malfunction indicator light can mean the sensor is worn, though a damaged wiring harness or connector can produce the same signs. With the engine off and cool, look both over for physical damage before you replace the sensor.
