Walker Products 250-24431 right oxygen sensor for the 1999 Volkswagen Jetta 4-cylinder 2.0L, the 2000-2001 Jetta 4-cylinder 1.8L and other vehicles measures the oxygen in the exhaust gas as a read on combustion efficiency. This Walker Products oxygen sensor is a direct-fit, 4-wire narrow-band unit.
- Monitors exhaust gases and reduces pollutants
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Oxygen readings let the air-fuel mixture be fine-tuned, which supports fuel economy
- Electrodes made of a gas-permeable platinum layer
- Made for a specific application and fitment position, with the diagnostic feedback the ECU requires
Quick facts
- Part: Walker Products 250-24431 oxygen sensor
- Fits: 1999 Volkswagen Jetta 4-cylinder 2.0L, the 2000-2001 Jetta 4-cylinder 1.8L and other vehicles
- Position: Upstream, downstream, downstream right
- Condition: New
A damaged wiring harness or connector can be behind poor running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light, just as a failed sensor can. Look the sensor, harness and connector over for physical damage with the engine off, and find the cause before buying a part.
Fits
This oxygen sensor also fits the 1999 Volkswagen Golf 4-cylinder 2.0L, the 2000-2001 Golf 4-cylinder 1.8L and the 2018-2022 Volkswagen Saveiro 4-cylinder 1.6L, with a single sensor per car. This listing is one sensor. If your car is not named here, open the "Vehicles it fits" section and look up your exact model and engine.

Frequently Asked Questions
Is this the right oxygen sensor for a 1999 VW Jetta 4-cylinder 2.0L?
Yes. Walker Products 250-24431 fits the 1999 Volkswagen Jetta 4-cylinder 2.0L and the 2000-2001 Jetta 4-cylinder 1.8L. For any other car, open the "Vehicles it fits" section.
Is this a 1999 VW Golf oxygen sensor for the 4-cylinder 2.0L?
Yes. This sensor fits the 1999 Volkswagen Golf 4-cylinder 2.0L and the 2000-2001 Golf 4-cylinder 1.8L, with one sensor per car.
Is the Walker Products 250-24431 a narrow-band or wide-band sensor?
The Walker Products 250-24431 is a narrow-band sensor with four wires. Its electrodes are made of a gas-permeable platinum layer.
Will a bad oxygen sensor store a fault code?
Yes, on newer vehicles the ECU stores fault codes, and some relate to the affected sensor and its associated systems. A shop can read them.
What does the coating on this Walker oxygen sensor protect?
The coating on this oxygen sensor guards the electrode surfaces against contamination and erosion from combustion residue and particulates in the exhaust gases.
