Walker Products 250-24470 oxygen sensor for the 2008-2009 Chevrolet Tahoe V8 4.8L, the 2008-2013 Tahoe V8 6.0L, the 2008-2014 Tahoe V8 5.3L, the 2009 Tahoe V8 6.2L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. This Walker Products oxygen sensor is a 4-wire, narrow-band, direct-fit unit.
A failing sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit check engine light. Before you replace it, look over the wiring harness and connector for physical damage and rule out other causes of those signs, since the sensor may not be at fault.
The vehicles it fits include the 2005-2009 Chevrolet Equinox V6 3.4L and, as a Chevy Silverado 1500 oxygen sensor, the 2007-2013 Chevrolet Silverado 1500 V8 4.8L, 5.3L or 6.0L and the 2009-2013 Silverado 1500 V8 6.2L. This listing is one sensor, and the 2005-2009 Equinox V6 3.4L takes one. If your vehicle is not named above, enter its year and engine on the Buyer's Guide tab to find it.
