Walker Products 350-34094 oxygen sensor for the 2004-2006 Chevrolet Malibu 4-cylinder 2.2L and other vehicles measures the amount of oxygen in the exhaust gas. It is a direct-fit narrow-band sensor made for its specific application and fitment position, and it gives the ECU the diagnostic feedback that application needs.

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