Walker Products 250-24091 oxygen sensor for the 1992-1993 Hyundai Elantra 4-cylinder 1.6L, the 1993 Elantra 4-cylinder 1.8L and other vehicles measures the oxygen content of the exhaust gas. As an upstream sensor, it monitors the air-fuel ratio for combustion efficiency.
- 4-wire narrow-band design made for its specific application and position on the vehicle
- Oxygen readings help fine-tune the air-fuel mixture and support fuel economy
- Monitors exhaust gases to help reduce pollutants
- Electrodes made of a gas-permeable platinum layer
- Coating guards the electrode surfaces against contamination and erosion from combustion residue and particulates
Quick facts
- Part: Walker Products 250-24091 oxygen sensor
- Fits: 1992-1993 Hyundai Elantra 4-cylinder 1.6L, 1993 Elantra 4-cylinder 1.8L and other vehicles

- Condition: New
A damaged wiring harness or connector can be behind a rough-running engine, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light, just as a failing oxygen sensor can. Look both over for physical damage and find the cause before you buy a sensor.

Frequently Asked Questions
Is this the oxygen sensor for the 1992-1993 Hyundai Sonata 4-cylinder 2.0L?
Yes. Walker Products 250-24091 is a direct-fit oxygen sensor for the 1992-1993 Hyundai Sonata 4-cylinder 2.0L, made for the upstream position.
Will this oxygen sensor fit the 1991-1992 Mitsubishi Galant 4-cylinder 2.0L?
Yes. Walker Products 250-24091 is a direct-fit upstream oxygen sensor for the 1991-1992 Mitsubishi Galant 4-cylinder 2.0L.
What thread does this Walker Products oxygen sensor have?
Walker Products 250-24091 has an M18 - 1.5 thread and sits in the upstream position. It is a 4-wire narrow-band sensor.
How can I tell if an upstream oxygen sensor is failing?
A failing sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light. Newer vehicles may also store a fault code in the ECU that a shop can read.
Is the 250-24091 sensor made for one specific application?
Yes. Every Walker Products part number is made for its specific application and fitment position, and it gives the diagnostic feedback the ECU requires.
