What could cause the check engine light to come on in a Acura MDX?

When your check engine light comes on, this could be as accepted as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a crucial problem that could cause crucial damage to your engine and come with a substantial repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow naturally means something less crucial but a flashing check engine light illustrates that your vehicle’s engine is in crucial trouble and service is needed abruptly. If your check engine light is flashing in your Acura MDX, we immensely recommend not to drive the vehicle and schedule Acura service now. Below is a list of the most common reasons your check engine light can come on:

  • One of the most legal and bountiful cause is that your Acura MDX gas cap is loose, damaged or missing. The gas cap for your 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 bad fuel cap? If your gas cap is old 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 fancy. If your check engine light turns on immediately after you put gas in your Acura MDX, first thing you should check is to make convinced the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your Acura MDX’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 David McDavid Acura in Plano offers a complimentary multi-point inspection with every Acura service. If you have an issue with your catalytic converter and don't get it serviced, your 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 extra problems from overheating.
  • Issues with each aftermarket items. An aftermarket alarm, exhaust or extra item can wreak havoc on your Acura MDX if it’s not installed well. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even impede the car from starting. If these issues sound aware, transport your MDX to Acura and have our unit of certified mechanics ensure that your aftermarket items were installed correctly and aren't causing each issue. Getting accessories, hugely 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 work and damage caused by poor installation work corrected.
  • Your Acura MDX has a vacuum leak. Every Acura MDX has a vacuum system that performs a big collection of functions. The vacuum system also helps lower bad 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, hugely if they’re exposed to exceptional heat or extreme brisk.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, known 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 car will be less instinctive 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 Acura MDX's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to learn the right 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.
  • New Spark Plugs or Plug Wires are essential for your Acura MDX. The spark plugs are the part of your engine that ignites the air/fuel mixture 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 old, 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, large to more fancy repairs.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Acura MDX is what determines how much fuel is essential 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 clear changes, like altitude. If your Acura MDX 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.
  • The battery is meager or dead. The battery in your Acura MDX is every notable. 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 Acura you travel to work, but check our current service coupons and specials.
