Oxygen Sensors

A properly working car depends on a constant flow of oxygen to stay functional. The fuel mixture in your Subaru needs a steady balance of oxygen in the exhaust and the oxygen sensor shows you just how balanced that mixture is. Your car won't immediately fail to perform if its oxygen balance is off, but naturally, you don't want this to go on unaddressed for too long. If you sense that you may be in need of a Subaru oxygen sensor replacement, get the parts you need sooner than later so you don't experience issues down the line. One thing you might notice is the check engine light coming on. While this can illuminate for a range of reasons, this is often the first line of defense when you have a failing or worn out oxygen sensor. Another thing to pay attention to is your fuel economy. Your fuel-delivery and combustion systems will be thrown off. There could be an issue with the air and fuel ratio in your vehicle, which could result in too much fuel injected into the engine. This can produce a rotten egg smell or generate smoke from your exhaust. Ensure you get an OEM Subaru oxygen sensor here on our site when you need a replacement.
