Though it's safe to drive with a broken o2 sensor for your Subaru Legacy, it's counterproductive to your vehicle's performance. It monitors the fuel to air ratio and tells the engine management computer to pull in fuel as needed. A broken sensor doesn't regulate fuel properly, and the computer usually overestimates the amount of fuel your engine needs. Solve your fuel efficiency problems today with a new oxygen sensor from AutoZone online. Choose Same Day Store Pickup (in most cases) to get your parts to you in no time.
