Below is a list of the most daily reasons your check engine light can come on:

  • One of the most commonplace and frequent cause is that your 2019 Jeep Cherokee gas cap is loose, damaged or missing. The gas cap for your 2019 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 erstwhile 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 expensive. If your check engine light turns on at this moment after you put gas in your 2019 Jeep Cherokee, first thing you should check is to make positive the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • Your 2019 Jeep Cherokee has a vacuum leak. Every Jeep Cherokee has a vacuum system that performs a expanded 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 dry out and crack, especially if they’re exposed to dominant heat or extreme freezing.
  • New Spark Plugs or Plug Wires are basic for your 2019 Jeep Cherokee. The spark plugs are the part of your engine that ignites the air/fuel collection in the combustion chamber of your car. 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 erstwhile, you will experience poor 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, essential to more expensive repairs.
  • 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 basic to run your engine efficiently by measuring the reward of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to authentic changes, like altitude. If your Jeep Cherokee is having trouble starting, idling rough or has a sudden change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2019 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 repaired, your 2019 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 distinctive problems from overheating.
  • The battery is poor or dead. The battery in your 2019 Jeep Cherokee is every big. 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 assorted decades ago, and they don't really require maintenance. The price of a new one depends on the type of Jeep you drive, but check our commonplace service coupons and specials.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or distinctive item can wreak havoc on your 2019 Jeep Cherokee if it’s not installed properly. These aftermarket parts and accessories can ditch the battery, trigger the check engine light, or even prevent the car from starting. If these issues sound beneficial, bring your Cherokee to Jeep and have our team of certified mechanics ensure that your aftermarket items were installed correctly and aren't causing any issue. Getting accessories, especially aftermarket parts and accessories, or using OEM parts first place might cost a little bit more but could save you money from having to get poor function and damage caused by poor installation function corrected.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, beneficial as the O2 sensor, measures the reward of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your car 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 2019 Jeep Cherokee's spark plugs.
