- 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
p>Your Nissan's combustion engine relies on numerous sensors and gauges to maintain the environment required for proper performance. One of these sensors is the O2 or Oxygen Sensor. Originally, they were introduced to help control and curb emissions, and are now a standard offering in most current vehicles. Depending on the Nissan model and year you own, your combustion engine may rely on one or more of these.
Your Oxygen Sensors help measure the air-to-fuel mixture, working with the internal computer to regulate the ratio 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 affect your engine combustion performance, resulting in decreased gas mileage and an increase in emissions. That's one reason why it's so important to get a high-quality Nissan Oxygen Sensor.
An Oxygen Sensor makes electricity, and the amount of voltage it results in depends on the product of the exhaust system. Simply put, the electricity generated by your Nissan Oxygen Sensor will vary if the fuel-air mixture is off! When the system notices a change in voltage, your vehicle's onboard computer adjusts the ratio to keep the combustion engine running as designed.
Your vehicle's O2 sensor may require a replacement due to age and wear. In certain circumstances, you may need to replace it prematurely if your Nissan sensor is damaged by coolant or oil leaks, or other forms of contamination. Some telltale signs that indicate the need for a replacement O2 sensor include: cylinder misfires, rough 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 moderate the combustion process, it can be challenging for vehicle owners to diagnose and repair this issue at home. Sometimes, the process involves a specialized code scanner and inspecting the undercarriage by jacking up the vehicle. That's why many Nissan drivers opt for getting O2 sensor replacement services with their local Nissan technicians.
