• Monitors the air-to-fuel ratio within your engine
• Can become worn over time or damaged by a fluid leak
• Replacement by an INFINITI professional is recommended

Your vehicle's combustion system depends on a variety of sensors to preserve an adequate environment for performance. One of these technologies if the Oxygen Sensor. At their inception, these sensors were invented to help limit emissions, and are now a standard offering in most current vehicles. Depending on the INFINITI model and year you own, you may have one or more of these in your engine.

The Oxygen Sensors help gauge your engine's air-to-fuel balance, working with the vehicle's computer to moderate the ratio depending on whether your engine is burning rich (too little oxygen) or too much oxygen (burning lean). Having the incorrect ratio of air-to-fuel can negatively impact the combustion system, resulting in reduced fuel efficiency and increased emissions. That's why it's a good idea to have a new INFINITI O2 sensor.

An Oxygen Sensor makes electricity, and the voltage it renders depends on what the exhaust system is producing. In layman's terms, the electricity generated by your INFINITI Oxygen Sensor varies if the air-to-fuel ratio is off. When a variance in voltage is detected, your engine's internal computer adjusts the ratio to keep it running as designed.

Your INFINITI Oxygen Sensor may need to be replaced due to regular wear and tear. In certain circumstances, your car may need a premature O2 sensor replacement if it's damaged due to leaks or other contaminants. Some telltale signs that indicate the need for a new INFINITI sensor include: cylinder misfires, loud idling, decreased fuel efficiency, and an illuminated check engine light.

Because most 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. In some cases, the process requires a specialized code scanner and inspecting the undercarriage by jacking up the vehicle. So many INFINITI drivers choose to get their Oxygen Sensor replacement services with their local INFINITI technicians.
