Walker Products 250-25051 left oxygen sensor for the 2011-2018 Porsche Cayenne V6 3.0L and other vehicles measures the oxygen content of the exhaust gas. This Walker Products oxygen sensor is made for its specific application and fitment position and returns the diagnostic feedback the ECU expects.
- Monitors exhaust gases and helps reduce pollutants
- Measures oxygen levels to help fine-tune the air-fuel mixture for fuel economy
- Tracks the air-fuel ratio in the exhaust for combustion efficiency
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Electrodes use a gas-permeable platinum layer
Quick facts
- Part: Walker Products 250-25051 left oxygen sensor
- Fits: 2011-2018 Porsche Cayenne V6 3.0L and other vehicles
- Position: Upstream, upstream left
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption, higher exhaust emissions or a lit malfunction indicator light. Before you replace this sensor, look over its wiring harness and connector for physical damage with the engine off, and have a shop read any stored fault codes, since other faults can set the same light.
Fits
As a Porsche Cayenne oxygen sensor replacement it is a direct-fit part for the 2011-2018 model with the V6 3.0L, and it also fits the 2012-2016 Porsche Panamera V6 3.0L and the 2011-2015 Volkswagen Touareg V6 3.0L.

Frequently Asked Questions
Is this the Porsche Cayenne oxygen sensor for a 2011-2018 Cayenne V6 3.0L?
Yes. Walker Products 250-25051 is listed for the 2011-2018 Porsche Cayenne V6 3.0L as the upstream left sensor. It fits other vehicles too, so check your own car in the "Vehicles it fits" section.
Is this Touareg oxygen sensor right for the 2011-2015 Volkswagen Touareg V6 3.0L?
Yes. Walker Products 250-25051 is listed for the 2011-2015 Volkswagen Touareg V6 3.0L in the upstream left position, and that position takes one sensor.
Is this oxygen sensor wide-band and heated?
Yes. This oxygen sensor is a heated wide-band unit with a threaded mount and a 1575 mm wiring harness.
What protects the electrodes of this wide-band oxygen sensor from exhaust residue?
A coating on the electrode surfaces guards them against contamination and erosion from combustion residue and particulates. The electrodes use a gas-permeable platinum layer.
Does this listing include both the left and right oxygen sensors?
No. This listing is one sensor for the upstream left position; the matching sensor on the other side is a separate part.
