Bosch 18113 left oxygen sensor for the 2010-2013 Ford Fusion 4-cylinder 2.5L and other vehicles measures the air-fuel ratio in the exhaust and reports it to the ECU. The ECU uses that signal to control the air-fuel mixture.

• Wideband design measures the air-fuel ratio continuously across the full lambda range
• Fast light-off, optimized heater control and ceramic construction for steady readings through rapid load changes and thermal cycles
• Handles exhaust gas up to 1,880°F; integrated heater element and TSP coating resist vibration, corrosion and contamination
• Reaches operating temperature in under 7 seconds for quick closed-loop control

A check engine light, poorer fuel economy or a rough idle can mean the oxygen sensor is wearing out. On their own those signs don't prove it, since a vacuum leak is another common cause.
