Walker Products Oxygen Sensor P/N:250-21051
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.
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.
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.
