Walker Products 250-24836 oxygen sensor for the 2005-2007 Chevrolet Equinox V6 3.4L and other vehicles reads the oxygen content of the exhaust gas. Each part number is made for its specific application and position and gives the ECU the diagnostic feedback it expects.
- Four-wire, narrow-band sensor with a direct-fit design
- Measures oxygen levels to fine-tune the air-fuel mixture for fuel economy
- Electrodes coated with a gas-permeable platinum layer
- Coating guards the electrode surfaces against contamination and erosion from combustion residue and exhaust particulates
- Monitors exhaust gases and helps reduce pollutants
Quick facts
- Part: Walker Products 250-24836 oxygen sensor
- Fits: 2005-2007 Chevrolet Equinox V6 3.4L and other vehicles
- Position: Downstream, upstream left, downstream left, downstream right, downstream front, downstream rear
- Condition: New
A damaged wiring harness or connector, or another exhaust or engine-management fault, can be behind rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. A failing sensor can show the same things, so find the cause before buying a sensor.
Fits
This sensor is listed for a wide range of Chevrolet, Buick, Pontiac and other makes' models, including the 2004-2005 Chevrolet Impala V6 3.8L and the 2005-2007 Buick LaCrosse V6 3.8L. This listing is one sensor, and the 2005-2007 Chevrolet Equinox V6 3.4L takes one. If your car is not named here, look up its year and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is Walker 250-24836 the right oxygen sensor for a 2004-2005 Chevrolet Impala V6 3.8L?
Yes. Walker Products 250-24836 is listed for the 2004-2005 Chevrolet Impala V6 3.8L, and that car takes one sensor.
Is this the right oxygen sensor for a 2005-2007 Chevrolet Equinox V6 3.4L?
Yes. Walker Products 250-24836 is listed for the 2005-2007 Chevrolet Equinox V6 3.4L. The "Vehicles it fits" section shows the other years and engines it covers.
Is this narrow-band sensor an upstream or downstream oxygen sensor?
This sensor is catalogued for these positions: downstream, upstream left, downstream left, downstream right, downstream front and downstream rear.
Can a bad narrow-band oxygen sensor set a check engine light?
Yes, it can. Newer vehicles store fault codes in the ECU, and some relate to the affected sensor and its systems. A shop can read those codes.
What does the platinum coating on a Walker Products oxygen sensor do?
The electrodes carry a gas-permeable platinum layer. That coating keeps combustion residue and exhaust particulates from contaminating or eroding the electrode surfaces.
