Walker Products 250-24495 oxygen sensor for the 1999-2005 Volkswagen Jetta 4-cylinder 2.0L and other vehicles measures the amount of oxygen in the exhaust gas. That reading shows how efficiently combustion is running.
- Narrow-band oxygen sensor with 4 wires
- Coating protects the electrode surfaces from combustion residue and particulates in the exhaust gases
- Electrodes made with a gas-permeable platinum layer
- Measures oxygen levels in the exhaust to help fine-tune the air-fuel ratio and fuel economy
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 250-24495 oxygen sensor
- Fits: 1999-2005 Volkswagen Jetta 4-cylinder 2.0L and other vehicles
- Position: Center, downstream, upstream left, upstream right, downstream left, downstream right
- Condition: New
A failing oxygen sensor can show up as a rough-running engine, higher fuel use, more exhaust emissions or a lit malfunction indicator light. A damaged wiring harness or connector can be behind those same signs, so look them over for physical damage with the engine off and trace the cause before you order a sensor.
Fits
This listing is one sensor. It is a direct-fit oxygen sensor for the 1999-2006 VW Golf 4-cylinder 2.0L, the 2001-2005 Volkswagen Beetle 4-cylinder 2.0L, the 2005 Beetle 4-cylinder 1.8L, the 2006-2010 Beetle 5-cylinder 2.5L and the 2007 Beetle 4-cylinder 2.0L, with one sensor per car. If your car is not named here, open the "Vehicles it fits" section and match your exact model and engine.

Frequently Asked Questions
Is this the right oxygen sensor for a 1999-2005 VW Jetta 4-cylinder 2.0L?
Yes. Walker Products 250-24495 is a direct-fit oxygen sensor for the 1999-2005 Volkswagen Jetta 4-cylinder 2.0L, and the car takes one. For other models, open the "Vehicles it fits" section.
Is this a 4-wire O2 sensor for the 1999-2005 VW Jetta 4-cylinder 2.0L?
Yes. Walker Products 250-24495 is a 4-wire narrow-band sensor, listed for the 1999-2005 Volkswagen Jetta 4-cylinder 2.0L.
What does the coating on this Walker Products oxygen sensor's electrodes do?
The coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases. The electrodes also carry a gas-permeable platinum layer.
What signs can show this oxygen sensor is failing?
A failed sensor can make the engine run poorly, raise fuel consumption and exhaust emissions, or light the malfunction indicator light.
Will a failing Walker Products 250-24495 oxygen sensor set fault codes?
On newer vehicles, fault codes are stored in the ECU, and some relate to the affected sensor and its systems. Each Walker Products sensor is made for its specific application to give the diagnostic feedback the ECU requires.
