A check engine light, rising fuel use or a rough idle can point to a tired sensor, though wiring, exhaust leaks or other parts can produce them too. With the engine off and cool, look over the harness and connector for cracks, melted insulation or oil residue before you buy. If the sensor is the cause, this one replaces it.
