When your check engine light comes on, this could be as simple as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a serious problem that could cause serious damage to your engine and come with a hefty repair bill. Depending on your make and model, the check engine light will illuminate or blink.

If your check engine light is flashing in your 2020 Honda Accord, we highly recommend not to drive the vehicle and schedule Honda service today. Below is a list of the most common reasons your check engine light can come on:

  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2020 Honda Accord’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 Coggin Honda Fort Pierce offers a complimentary multi-point inspection with every Honda service. If you have an issue with your catalytic converter and don't get it repaired, your 2020 Honda Accord 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 added problems from overheating.
  • New Spark Plugs or Plug Wires are needed for your 2020 Honda Accord. 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 traditional, you will experience poor performance and reduced power. In a little 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, major to more expensive repairs.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, aware 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 usable when it comes to fuel economy.
  • One of the most typical and many cause is that your 2020 Honda Accord gas cap is loose, damaged or missing. The gas cap for your 2020 Honda Accord 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 traditional 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 immediately after you put gas in your 2020 Honda Accord, earliest 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.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or added item can wreak havoc on your 2020 Honda Accord if it’s not installed properly. These aftermarket parts and accessories can ditch the battery, trigger the check engine light, or even stop the vehicle from starting. If these issues sound aware, bring your Accord to Honda and have our company of certified mechanics ensure that your aftermarket items were installed correctly and aren't causing any issue. Getting accessories, remarkably aftermarket parts and accessories, or using OEM parts earliest place might cost a scant bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Honda Accord 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 firm changes, like altitude. If your Honda Accord 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.
  • 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 2020 Honda Accord's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to indicate the good 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.
  • The battery is low or dead. The battery in your 2020 Honda Accord is every hefty. 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 little decades ago, and they don't really require maintenance. The price of a new one depends on the type of Honda you drive, but check our contemporary service coupons and specials.
  • Your 2020 Honda Accord has a vacuum leak. Every Honda Accord has a vacuum system that performs a wide variety of functions. The vacuum system also helps cut 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, remarkably if they’re exposed to important heat or extreme chilled.

When the light turns on, the ECM stores an engine code or “trouble code” in its memory that identifies as the issue, whether it's a sensor or a failing engine part. This code is read with an electronic scan tool that is used by our Honda auto repair mechanics at Coggin Honda Fort Pierce. There are also a number of relatively inexpensive code readers that are designed for do-it-yourselfers, should you choose that route too. While this code will tell you the issue that is detected, a true diagnosis still requires an experienced professional to determine the issue and repair it.
