If your check engine light is twinkling in your 2018 Acura MDX, we highly advise not to drive the vehicle and schedule Acura service today. Below is a list of the most common reasons your check engine light can come on:

  • The battery is low or dead. The battery in your 2018 Acura MDX is every imposing. 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 price of a new one depends on the type of Acura you drive, but check our accepted service coupons and specials.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak havoc on your 2018 Acura MDX if it’s not installed appropriately. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound commonplace, bring your MDX to Acura and have our team of certified mechanics ensure that your aftermarket items were installed correctly and aren't causing any issue. Getting accessories, highly aftermarket parts and accessories, or using OEM parts first place might cost a equitable bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
  • Your O2 Sensor (Oxygen Sensor) needs to be replenished. The Oxygen sensor, commonplace 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 functional 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 Acura MDX's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the right mixture of air and fuel that enters the cylinders in your engine. A detrimental O2 sensor can also cause a car to fail an emissions test.
  • Your mass airflow sensor (known as MAF) needs to be replenished. The mass airflow sensor in your Acura MDX is what determines how much fuel is necessary 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 attentive changes, like altitude. If your Acura MDX is having trouble starting, idling rough or has a precipitous change in the position of the throttle pedal, this could be a sign of a detrimental mass airflow sensor.
  • Your catalytic converter is detrimental or going detrimental. The catalytic converter is a part of your 2018 Acura MDX’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 Nalley Acura offers a complimentary multi-point inspection with every Acura service. If you have an issue with your catalytic converter and don't get it repaired, your 2018 Acura MDX 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 other problems from overheating.
  • New Spark Plugs or Plug Wires are necessary for your 2018 Acura MDX. 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 detrimental or departed, 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, big to more expensive repairs.
  • One of the most accepted and many cause is that your 2018 Acura MDX gas cap is loose, damaged or missing. The gas cap for your 2018 Acura MDX 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 detrimental 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 expensive. If your check engine light turns on quickly after you put gas in your 2018 Acura MDX, 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.
  • Your 2018 Acura MDX has a vacuum leak. Every Acura MDX has a vacuum system that performs a expansive variety of functions. The vacuum system also helps decrease 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, highly if they’re exposed to important heat or extreme cold.

Will the check engine light reset itself?

The check engine light on your 2018 Acura MDX will generally shut itself off if the issue or code that caused it to turn on is fixed. For example, if the cause of your check engine light coming on was a loose gas cap, if it's tightened, the light will turn itself off. Likewise, if your catalytic converter is going active, and you did a lot of stop-and-go driving, that may have turned on the check engine light due to the high usage of the converter. In most cases, your 2018 Acura MDX light will go off after about 20-40 miles. If you drive over that reward and the light is still on, you will need to transport it in to Nalley Acura so the light and code can be double-checked and reset.
