Nissan Altima Oxygen Sensor
Nissan designed your Altima for comfort and economy, which makes it the perfect commuter car. A sudden drop in your miles per gallon is an indication of a poor air-to-fuel ratio, which is regulated by the Altima O2 sensor and the electronic control unit. Replace the sensor every 30,000 to 50,000 miles to prevent this problem.

The sensors in the system identify issues as they arise and send the message to the electronic control unit. When an Altima oxygen sensor fails, the ECU doesn't know how much oxygen is in the exhaust, and fuel adjustments aren't made. Then the engine runs too rich or too lean and causes stalling, rough idle or increased emissions. Nissan Altima replacement oxygen sensors are typically all you need to correct the problem, and AutoAnything stocks them at low prices with a 1-Year, Lower Price Guarantee included.
