Walker Products 350-34549 oxygen sensor for the 1990-1994 Plymouth Laser 4-cylinder 2.0L and other vehicles measures the oxygen in the exhaust gas. This upstream Walker Products oxygen sensor is made for its specific application and fitment position, and it gives the ECU the diagnostic feedback it requires.

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