Walker Products 250-25112 oxygen sensor for the 2015-2018 Volkswagen Jetta 4-cylinder 2.0L and other vehicles measures the oxygen in the exhaust gas to show combustion efficiency. Every part number is made for its own application and position and gives the ECU the diagnostic feedback it needs.
- 5-wire wide-band design that determines the oxygen content of the exhaust gas
- Electrodes made of a gas-permeable platinum layer
- Measures oxygen levels to help fine-tune the air-fuel mixture and fuel economy
- Monitors exhaust gases to help reduce pollutants
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
Quick facts
- Part: Walker Products 250-25112 oxygen sensor
- Fits: 2015-2018 Volkswagen Jetta 4-cylinder 2.0L and other vehicles
- Position: Upstream, upstream left, upstream right, upstream front
- Condition: New
A failing sensor can make the engine run poorly, use more fuel or light the malfunction indicator light. Other faults cause the same signs, so with the engine off and cool, look over the sensor, wiring harness and connector for physical damage before you replace it.

Frequently Asked Questions
Is this the oxygen sensor for a 2015-2018 VW Jetta 4-cylinder 2.0L?
Yes. Walker Products 250-25112 is listed for the 2015-2018 Volkswagen Jetta 4-cylinder 2.0L, and the vehicle takes one sensor.
Is this VW Tiguan oxygen sensor right for the 2018-2019 Tiguan 4-cylinder 2.0L?
Yes. The 2018-2019 Volkswagen Tiguan 4-cylinder 2.0L is in the fitment for Walker Products 250-25112, one sensor per vehicle. Open the "Vehicles it fits" section to check other models.
Is this Walker Products oxygen sensor a wide-band or narrow-band type?
Wide-band, with five wires. It tracks the air-fuel ratio from the oxygen in the exhaust gas.
Will a failed oxygen sensor store a fault code on newer cars?
Newer vehicles store fault codes in the ECU, and some relate to the affected sensor and its systems. A shop can read them with a scan tool.
Is this an upstream or downstream oxygen sensor?
Upstream. Walker Products 250-25112 is listed as upstream, including the upstream left, upstream right and upstream front positions.
