Walker Products 250-24692 oxygen sensor for the 2005-2009 Volkswagen Jetta 5-cylinder 2.5L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. This narrow-band, four-wire, direct-fit sensor sits downstream and passes its reading to the engine control unit.
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and exhaust particulates
- Oxygen content of the exhaust gas is monitored to track the air-fuel ratio for combustion efficiency
- Oxygen readings help fine-tune the air-fuel mixture
- Electrodes use a gas-permeable platinum layer
- Exhaust gas monitoring helps reduce pollutants
Quick facts
- Part: Walker Products 250-24692 oxygen sensor
- Fits: 2005-2009 Volkswagen Jetta 5-cylinder 2.5L and other vehicles
- Position: Downstream, downstream left, downstream right
- Condition: New
A damaged wiring harness or connector can be behind a rough-running engine, higher fuel use, more exhaust emissions or a lit malfunction indicator light, and so can a failed sensor. Find the cause before buying; with the engine off and cool, look the sensor, harness and connector over for physical damage.
Fits
Walker Products lists this sensor for a range of Volkswagen and Audi models, including the 2005-2009 Volkswagen Jetta 5-cylinder 2.5L, the 2010-2011 Volkswagen Golf 5-cylinder 2.5L and the 2013-2015 Audi RS5 V8 4.2L. This listing is one sensor, and the application takes one at this position.

Frequently Asked Questions
Is this the right oxygen sensor for a 2005-2009 VW Jetta 5-cylinder 2.5L?
Yes, Walker Products 250-24692 is listed for the 2005-2009 Volkswagen Jetta 5-cylinder 2.5L. If your car is not named on this page, look it up in the "Vehicles it fits" section.
Is this the VW Golf oxygen sensor for the 2010-2011 Golf 5-cylinder 2.5L?
Yes, it is listed for the 2010-2011 Volkswagen Golf 5-cylinder 2.5L. The application takes one sensor.
Is this Walker Products oxygen sensor narrow-band or wideband?
Walker Products 250-24692 is a narrow-band sensor with four wires. It is a direct-fit sensor for the applications it is listed for.
Can a failing downstream oxygen sensor turn on the check engine light?
Yes, a failed sensor can light the malfunction indicator light. It can also bring rough running, higher fuel use or more exhaust emissions, and newer vehicles store fault codes in the ECU.
What does the coating on this oxygen sensor protect?
The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases. The electrodes use a gas-permeable platinum layer.
