- Monitors the air-to-fuel ratio within your engine
- Can become worn over time or damaged by a fluid leak
- Replacement by an Nissan professional is recommended
Your vehicle's combustion system depends on various sensors to maintain an adequate environment for performance. One of these sensors if the Oxygen Sensor. At their inception, they were introduced to help control and curb emissions, and are now standard in most modern vehicles. Depending on which Nissan model and year you drive, your engine may have one or more sensors.
Your Oxygen Sensors help measure the air-to-fuel mixture, working with the internal computer to regulate the mixture depending on whether your engine is running on too little oxygen (burning rich) or burning lean (too much oxygen). An “off” air-to-fuel ratio can negatively impact the combustion system, leading to reduced fuel efficiency and more emissions. That's why it's smart to get a high-quality Nissan Oxygen Sensor.
An Oxygen Sensor produces an electric charge, and the amount of voltage it creates depends on the product of the exhaust system. In layman's terms, the electricity generated by your Nissan Oxygen Sensor varies if the air-to-fuel ratio is off. When the system notes a variance in voltage, your engine's internal computer makes adjustments to the fuel mixtures to keep it running as designed.
Your Nissan Oxygen Sensor may need to be replaced after a period of time or usage. In some cases, your car may need a premature O2 sensor replacement if your Nissan sensor is damaged by coolant or oil leaks, or other contaminants. Some symptoms that may clue you into the need for a replacement O2 sensor include: engine misfires, noisy idling, poor gas mileage, and an illuminated dashboard warning light.
Since the majority of modern cars rely on not one but multiple Oxygen Sensors to support proper combustion, it can be hard for vehicle owners to diagnose and repair this issue at home. Occasionally, the process involves a specialized code scanner and lifting the vehicle up on jacks to get a clear view of the undercarriage. Accordingly, most Nissan owners opt for getting Oxygen Sensor repairs at their local Nissan service center.
