Walker Products 350-34294 oxygen sensor for the 1998 Hyundai Elantra 4-cylinder 1.8L, the 1999-2000 Elantra 4-cylinder 2.0L and other vehicles measures the oxygen in the exhaust gas and reports it to the ECU. It is a direct-fit upstream sensor with a narrow-band, 4-wire design.
- Monitors exhaust gases and helps reduce pollutants for a cleaner environment
- Monitors 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
- Electrodes made of a gas-permeable platinum layer
- Oxygen readings help fine-tune the air-fuel mixture to support fuel economy
Quick facts
- Part: Walker Products 350-34294 oxygen sensor
- Fits: the 1998 Hyundai Elantra 4-cylinder 1.8L, the 1999-2000 Elantra 4-cylinder 2.0L and other vehicles
- Position: Upstream
- Condition: New
A failing sensor can make the engine run poorly, raise fuel consumption and exhaust emissions, or turn on the malfunction indicator light. Those signs can have other causes, so with the engine off and cool, first look the sensor, wiring harness and connector over for physical damage.
Fits
This sensor also fits the 1998-2001 Hyundai Tiburon 4-cylinder 2.0L and the 1997-1999 Hyundai Accent 4-cylinder 1.5L. These cars need one sensor each, and this listing is a single sensor.

Yes. Walker Products 350-34294 fits the 1997-1999 Hyundai Accent 4-cylinder 1.5L, and that car takes one.
Is this Elantra oxygen sensor right for the 1998 Hyundai Elantra 4-cylinder 1.8L and the 1999-2000 Elantra 4-cylinder 2.0L?
Yes. Walker Products 350-34294 fits the 1998 Hyundai Elantra 4-cylinder 1.8L and the 1999-2000 Hyundai Elantra 4-cylinder 2.0L.
Is this Walker Products oxygen sensor narrow-band or wideband?
It is a narrow-band sensor with a 4-wire design. It has a coating that protects the electrode surfaces from combustion residue and particulates.
Can a failed upstream oxygen sensor store a fault code in the ECU?
Yes, it can. Newer vehicles store fault codes in the ECU, and some of them relate to the affected sensor and its associated systems.
Is the Walker Products 350-34294 an upstream sensor, and how many does the car take?
Yes, Walker Products 350-34294 is an upstream sensor. This listing is one sensor, and the cars it fits take one.
