Oxygen Sensor for 1989-1991 Hyundai Sonata & More - Walker 250-22002

Walker Products 250-22002 oxygen sensor for the 1989-1991 Hyundai Sonata 4-cylinder 2.4L and other vehicles measures the oxygen in the exhaust gas. This upstream Walker Products oxygen sensor is a narrow-band, specific-fit unit made for its application and fitment position, and it gives the ECU the diagnostic feedback it expects.

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

A sensor on its way out can show up as an engine that runs poorly, higher fuel consumption or a lit malfunction indicator light. Because a worn sensor is only one possible source of those symptoms, start with a look at the sensor, wiring harness and connector for physical damage, with the engine off and cool.
