Walker Products 250-24773 oxygen sensor for the 2008-2009 Chevrolet Equinox V6 3.6L and other vehicles measures the oxygen in the exhaust gas. This Walker Products oxygen sensor is a narrow-band, 4-wire unit made for its specific application and fitting position.
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust
- Electrodes carry a gas-permeable platinum layer
- Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency
- Monitors exhaust gases to help reduce pollutants
- Narrow-band, 4-wire sensor with an M18 - 1.5 thread
Quick facts
- Part: Walker Products 250-24773 oxygen sensor
- Fits: 2008-2009 Chevrolet Equinox V6 3.6L and other vehicles
- Condition: New
A failing oxygen sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light. Before you replace the sensor, look the wiring harness and connector over for physical damage and rule out other causes of those symptoms.
Fits
The 2008-2009 Chevrolet Equinox V6 3.6L, 2012-2016 GMC Acadia V6 3.6L and 2014-2020 Chevrolet Impala V6 3.6L all take this oxygen sensor, and so do other vehicles.

Frequently Asked Questions
Is this a Chevy Equinox oxygen sensor replacement for a 2008-2009 Equinox V6 3.6L?
Yes. Walker Products 250-24773 fits the 2008-2009 Chevrolet Equinox V6 3.6L, and that engine takes one sensor.
Is this the GMC Acadia oxygen sensor for a 2012-2016 Acadia V6 3.6L?
Yes, the 2012-2016 GMC Acadia V6 3.6L is on the fitment list. For other years or engines, open the "Vehicles it fits" section.
What thread size does this narrow-band Walker oxygen sensor have?
Walker Products 250-24773 has an M18 - 1.5 thread and a threaded body. It is a narrow-band sensor with four wires.
Can a bad oxygen sensor raise fuel use or turn on the check engine light?
Yes, it can. A failed sensor can make the engine run poorly, use more fuel, raise exhaust emissions or turn on the malfunction indicator light.
What does the coating on this oxygen sensor protect?
The coating keeps combustion residue and particulates in the exhaust from contaminating and eroding the electrode surfaces. The electrodes also have a gas-permeable platinum layer.
