Is it time to replace your Nissan Altima Oxygen Sensor? If you suddenly find yourself spending a lot more on gas, or if your engine is surging and/or hesitating for no apparent reason, you may need a new O2 sensor. A broken oxygen sensor will also lead to unacceptable levels of emissions and is a common explanation for a failed emissions test. Experts recommend replacing your O2 sensor every 60,000 miles to prevent unnecessary wear on your catalytic converter and keep your engine working most efficiently.

Even a moderately driven car produces millions of gallons of exhaust every week. Your oxygen sensor helps make sure all that exhaust is as clean as possible.

It also makes sure your engine uses exactly as much gas as it’s supposed to for your Altima to run at peak efficiency. The O2 sensor works by introducing a tiny electric charge into your exhaust and constantly checking voltage levels with a voltage meter. It sends these readings back to your computer, which uses this information to determine the ratio of air to gasoline your engine is using. To maintain optimum efficiency your engine should use exactly 14.7 times as much air as it does gas. Your computer monitors the readings from your oxygen sensor and adjusts the fuel injection settings to keep this ratio as close to perfect as possible. To add life to your engine and keep your Altima running its best, replace your Nissan Altima Oxygen Sensor before it wears out.
