Walker Products 250-25036 right oxygen sensor for the 2004-2005 Volkswagen Jetta 4-cylinder 1.9L and other vehicles measures the oxygen content of the exhaust gas. This Walker Products oxygen sensor is a wide-band unit made for its specific application and fitment position, and it gives the ECU the diagnostic feedback it requires.
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust
- Electrodes made of a gas-permeable platinum layer
- Monitors the air-fuel ratio for combustion efficiency
- Measures oxygen levels so the air-fuel mixture can be fine-tuned for fuel economy
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 250-25036 oxygen sensor
- Fits: 2004-2005 Volkswagen Jetta 4-cylinder 1.9L and other vehicles
- Position: Upstream, downstream, upstream right
- Condition: New
A failing oxygen sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. These signs alone do not prove the sensor is at fault, since an exhaust leak can also skew the readings. The sensor, wiring harness and connector can also be inspected for physical damage.
Fits
It is an oxygen sensor for the 2004-2005 Volkswagen Jetta 4-cylinder 1.9L, the 2004-2005 Passat 4-cylinder 2.0L and the 2004-2006 Golf 4-cylinder 1.9L. This listing is one sensor, and the 2004-2005 Jetta 4-cylinder 1.9L takes one. Open the "Vehicles it fits" section to check your exact model and engine.

Frequently Asked Questions
Is this the oxygen sensor for a 2004-2005 VW Jetta 4-cylinder 1.9L?
Yes. Walker Products 250-25036 fits the 2004-2005 Volkswagen Jetta 4-cylinder 1.9L, and that Jetta takes one sensor.
Is this a VW Golf oxygen sensor for the 2004-2006 Golf 4-cylinder 1.9L?
Yes. Walker Products 250-25036 fits the 2004-2006 Volkswagen Golf 4-cylinder 1.9L. Open the "Vehicles it fits" section to check other models and engines.
What type of sensor is the Walker Products 250-25036?
It is a wide-band oxygen sensor with electrodes made of a gas-permeable platinum layer.
What does the coating on this oxygen sensor do?
The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases.
What symptoms can a failing wide-band oxygen sensor cause?
It can lead to poor engine running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. A shop can read the stored fault codes to narrow down the cause.
