Walker Products 250-24689 oxygen sensor for the 2010 Volkswagen Jetta 4-cylinder 1.8L and other vehicles measures the oxygen in the exhaust gas. That reading shows how efficiently combustion is working.
- Made for its application and sensor position, with the diagnostic feedback the ECU expects
- Monitors exhaust gases and reduces pollutants for a cleaner environment
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Measures oxygen levels to help fine-tune the air-fuel mixture and support fuel economy
- Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio
- Electrodes coated with a gas-permeable platinum layer
Quick facts
- Part: Walker Products 250-24689 oxygen sensor
- Fits: 2010 Volkswagen Jetta 4-cylinder 1.8L and other vehicles
- Position: Upstream, downstream, downstream left, downstream right
- Condition: New
A failed sensor can make the engine run poorly, raise fuel consumption and exhaust emissions, or turn on the malfunction indicator light. These signs alone do not prove the sensor is at fault, because a worn spark plug can also make an engine run poorly. Look the sensor, wiring harness and connector over for physical damage.
Fits
The 2010 Volkswagen Jetta 4-cylinder 1.8L, the 2004-2006 Audi A8 Quattro V8 4.2L and the 2005-2009 A8 Quattro W12 6.0L, and the 2004-2009 Audi S4 V8 4.2L are among the vehicles this sensor fits, along with many others. Each fitment calls for one sensor, and this listing is one sensor. If your car is not named here, you can look it up in the "Vehicles it fits" section.

Frequently Asked Questions
Is this the right oxygen sensor for a 2010 VW Jetta 4-cylinder 1.8L?
Yes. Walker Products 250-24689 fits the 2010 Volkswagen Jetta 4-cylinder 1.8L. This listing is one sensor, and the fitment calls for one.
Is this an Audi S4 oxygen sensor for 2004-2009 cars with the V8 4.2L engine?
Yes. Walker Products 250-24689 is listed for the 2004-2009 Audi S4 V8 4.2L. For any other car, look it up in the "Vehicles it fits" section.
What type is this Walker Products oxygen sensor?
Walker Products 250-24689 is a 4-wire, narrow-band sensor with an M18 - 1.5 thread.
Will a bad oxygen sensor like this one store a fault code?
It can. Newer vehicles store fault codes in the ECU, and some relate to the affected sensor. A shop can read them to help find the cause.
Does this oxygen sensor have a protective coating?
Yes. A coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases. The electrodes carry a gas-permeable platinum layer.
