Walker Products 250-24491 oxygen sensor for the 2003-2006 Chevrolet Silverado 1500 V8 6.0L and other vehicles measures the oxygen in the exhaust gas as a gauge of combustion efficiency. This Walker Products oxygen sensor is a 4-wire, narrow-band unit made for its specific application and fitment position.
Poor running, higher fuel consumption or a lit malfunction indicator light can be signs of a failed sensor, though other faults can show the same way. With the engine off and cool, look over the sensor, its wiring harness and its connector for physical damage before you replace it.
The vehicles it fits include the 2003-2006 Chevrolet Silverado 1500 V8 6.0L, the 2010-2015 Chevrolet Camaro V8 6.2L and the 2014-2015 Camaro V8 7.0L, and the 2003-2006 GMC Sierra 1500 V8 6.0L, all as direct-fit applications with a quantity of one. This listing is a single sensor.

Does this Camaro oxygen sensor fit both the 2010-2015 Chevrolet Camaro V8 6.2L and the 2014-2015 Camaro V8 7.0L?
Yes. It fits the 2010-2015 Chevrolet Camaro V8 6.2L and the 2014-2015 Camaro V8 7.0L.
What kind of oxygen sensor is Walker Products 250-24491, and what thread does it have?
Walker Products 250-24491 is a narrow-band, direct-fit sensor with four wires and an M18 - 1.5 thread.
Will a bad oxygen sensor store a fault code or raise exhaust emissions?
Yes, it can. A failed sensor might increase exhaust emissions, and newer vehicles store fault codes in the ECU, some tied to the affected sensor and its associated systems.
What protects the platinum electrodes on this oxygen sensor?
A coating over the electrodes' gas-permeable platinum layer prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases.
