Walker Products 250-24649 oxygen sensor for the 2010-2012 Chevrolet Equinox V6 3.0L, the 2013-2017 Equinox V6 3.6L and other vehicles measures the oxygen content of the exhaust gas. It is a direct-fit, narrow-band sensor with four wires that tracks the air-fuel ratio and combustion efficiency.
- Measures exhaust oxygen 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
- Electrodes made of a gas-permeable platinum layer
Quick facts
- Part: Walker Products 250-24649 oxygen sensor
- Fits: 2010-2012 Chevrolet Equinox V6 3.0L, the 2013-2017 Equinox V6 3.6L and other vehicles
- Position: downstream, upstream left, upstream right, downstream left, downstream right, upstream rear, upstream front, downstream front, downstream rear
- Condition: New
A failing sensor can show up as rough running, higher fuel use or a lit malfunction indicator light. Before you replace the sensor, rule out physical damage to its wiring harness and connector, which can give similar signs.
Fits
The 2009-2011 GMC Acadia V6 3.6L, the 2010-2012 GMC Terrain V6 3.0L and the 2013-2017 Terrain V6 3.6L are among the vehicles this sensor fits, and many more share it. Use it as a GMC Acadia oxygen sensor on the 2009-2011 V6 3.6L, or open the "Vehicles it fits" section to check your exact model and engine. Each sensor position takes one sensor, and this listing is one.

Frequently Asked Questions
Is this a Chevy Equinox oxygen sensor replacement for the 2010-2012 Equinox V6 3.0L and the 2013-2017 Equinox V6 3.6L?
Yes. Walker Products 250-24649 is listed for the 2010-2012 Chevrolet Equinox V6 3.0L and the 2013-2017 Equinox V6 3.6L, with one sensor per application.
Does this GMC Terrain oxygen sensor fit a 2010-2012 Terrain V6 3.0L or a 2013-2017 Terrain V6 3.6L?
Yes. The 2010-2012 GMC Terrain V6 3.0L and the 2013-2017 Terrain V6 3.6L are both listed for this oxygen sensor.
Is the Walker 250-24649 a narrow-band or wideband sensor?
Walker Products 250-24649 is a narrow-band oxygen sensor with four wires, sold as a direct-fit part.
What problems can a failing oxygen sensor like this one cause?
Rough running, higher fuel use or more exhaust emissions can go with a failing sensor, though other problems can bring on those symptoms too.
What does the coating on this oxygen sensor's electrodes do?
The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas. The electrodes are a gas-permeable platinum layer.
