What could cause the check engine light to come on in a 2018 Jeep Cherokee?

When your check engine light comes on, this could be as effortless as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a perilous problem that could cause perilous damage to your engine and come with a big repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow typically means something less perilous but a glaring check engine light illustrates that your vehicle’s engine is in perilous trouble and service is essential shortly. If your check engine light is glaring in your 2018 Jeep Cherokee, we highly advocate not to drive the vehicle and schedule Jeep service today. Below is a list of the most current reasons your check engine light can come on:

  • New Spark Plugs or Plug Wires are needed for your 2018 Jeep Cherokee. The spark plugs are the part of your engine that ignites the air/fuel mixture in the combustion chamber of your vehicle. This explosion is what moves the pistons and makes the engine run. The spark plug wires deliver the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are bad or classical, you will experience slight performance and reduced power. 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, large to more costly repairs.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2018 Jeep Cherokee’s exhaust system. The catalytic converter's function 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 Crown Chrysler Dodge Jeep Ram Greensboro offers a complimentary multi-point inspection with every Jeep service. If you have an issue with your catalytic converter and don't get it fixed, your 2018 Jeep Cherokee 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 extra problems from overheating.

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 dry out and crack, especially if they’re exposed to extraordinary heat or extreme cold.
  • The battery is low or dead. The battery in your 2018 Jeep Cherokee is every exciting. 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 innumerable decades ago, and they don't entirely require maintenance. The price of a new one depends on the type of Jeep you drive, but check our existing service coupons and specials.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, accepted as the O2 sensor, measures the amount of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less active 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 2018 Jeep Cherokee's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to choose the correct mixture of air and fuel that enters the cylinders in your engine. A bad O2 sensor can also cause a car to fail an emissions test.
  • One of the most accepted and frequent cause is that your 2018 Jeep Cherokee gas cap is loose, damaged or missing. The gas cap for your 2018 Jeep Cherokee 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 classical 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 costly. If your check engine light turns on rapidly after you put gas in your 2018 Jeep Cherokee, first thing you should check is to make confident the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • Issues with all aftermarket items. An aftermarket alarm, exhaust or extra item can wreak havoc on your 2018 Jeep Cherokee if it’s not installed properly. These aftermarket parts and accessories can dump the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound common, bring your Cherokee to Jeep and have our team of certified technicians ensure that your aftermarket items were installed correctly and aren't causing all issue. Getting accessories, especially aftermarket parts and accessories, or using OEM parts first place might cost a small bit more but could save you money from having to get slight work and damage caused by slight installation work corrected.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Jeep Cherokee is what determines how much fuel is needed to run your engine efficiently by measuring the amount of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to noteworthy changes, like altitude.
