If there is excess oxygen in your exhaust system, fuel burns faster and your automobile will be less direct when it comes to fuel economy. So what happens if I don’t replace your O2 sensor? A faulty sensor can not only affect your miles per gallon, but it can cause damage to your catalytic converter and your 2017 Nissan Sentra's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to learn the humane mixture of air and fuel that enters the cylinders in your engine.

In some extreme cases, your engine will have trouble starting or continuing to run. Worn spark plugs and plug wires can cause clogged catalytic converter or damage to ignition coils and O2 sensors, first-rate to more pricey repairs.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2017 Nissan Sentra’s exhaust system. The catalytic converter's work is to turn the carbon monoxide created by the combustion process into carbon dioxide. A damaged catalytic converter is usually caused by neglected maintenance, which is why Coggin Nissan on Atlantic offers a complimentary multi-point inspection with every Nissan service. If you have an issue with your catalytic converter and don't get it repaired, your 2017 Nissan Sentra will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your car may run at a higher temperature, too, which can cause supplemental problems from overheating.
  • One of the most prevalent and bountiful cause is that your 2017 Nissan Sentra gas cap is loose, damaged or missing. The gas cap for your 2017 Nissan Sentra serves multiple purposes. It prevents gas fumes from being released when you aren't driving, it seals the fuel system and helps maintain pressure within the fuel tank. What happens if you have a bad fuel cap? If your gas cap is departed or has a ruptured seal, you can lose fuel through evaporation which will result in more trips to the pump. Luckily, to replace a gas cap isn't pricey. If your check engine light turns on urgently after you put gas in your 2017 Nissan Sentra, first thing you should check is to make sure the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • The battery is low or dead. The battery in your 2017 Nissan Sentra is every useful. Without a car battery, your car won’t start, light up the road ahead, play the radio or charge your phone. Today’s car batteries last much longer than they did a few decades ago, and they don't really require maintenance. The estimate of a new one depends on the type of Nissan you drive, but check our normal service coupons and specials.
  • Your 2017 Nissan Sentra has a vacuum leak. Every Nissan Sentra has a vacuum system that performs a wide variety of functions. The vacuum system also helps lower harmful emissions by routing the fumes as gasoline evaporates through the engine. If you notice that your RPM is high in idle or randomly surges, a vacuum leak could be the cause. Over time, vacuum hoses can arid out and crack, chiefly if they’re exposed to important heat or extreme exasperated.
