Walker Products 250-24843 right oxygen sensor for the 2004 Volkswagen Jetta 4-cylinder 2.0L and other vehicles measures exhaust oxygen to gauge combustion efficiency. This Walker Products oxygen sensor is a 4-wire, direct-fit, narrow-band unit.
- Made for its specific application and fitment position, with the diagnostic feedback the ECU requires
- Monitors exhaust gases to help keep pollutants down
- 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
- Measures oxygen levels so the air-fuel mixture can be fine-tuned, which helps fuel economy
Quick facts
- Part: Walker Products 250-24843 oxygen sensor
- Fits: 2004 Volkswagen Jetta 4-cylinder 2.0L and other vehicles
- Position: Upstream, downstream, downstream right
- Condition: New
A failing sensor can show up as rough running, higher fuel use or a lit malfunction indicator light. Before you replace it, look over the wiring harness and connector for physical damage, since those signs can come from other causes too.
Fits
It also fits the 2000 Volkswagen Passat 4-cylinder 1.8L and, as a Touareg oxygen sensor, the 2004-2007 Volkswagen Touareg V8 4.2L and the 2005 Touareg V6 3.2L. This listing is one sensor, and each application calls for a single one. If your car is not named here, run its year, make and model through the "Vehicles it fits" section to see whether this sensor is a match.

Frequently Asked Questions
Is this the right oxygen sensor for a 2004 VW Jetta 4-cylinder 2.0L?
Yes. Walker Products 250-24843 is listed for the 2004 Volkswagen Jetta 4-cylinder 2.0L, and that application takes one sensor.
Is this a Passat oxygen sensor for the 2000 Volkswagen Passat 4-cylinder 1.8L?
Yes. The 2000 Volkswagen Passat 4-cylinder 1.8L is in this sensor's fitment, and it takes one.
What thread does Walker Products 250-24843 have?
Walker Products 250-24843 has an M18 - 1.5 thread. It is a 4-wire sensor made for its specific application and fitment position.
Can a failing oxygen sensor like this one set a fault code?
Yes. Newer vehicles store fault codes in the ECU, and some relate to the affected sensor and its associated systems. A shop can read them.
Is this oxygen sensor wideband or narrow-band?
Narrow-band. This sensor has four wires and determines the oxygen content of the exhaust gas to monitor the air-fuel ratio.
