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

  • 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 more immediately and your car will be less efficient when it comes to fuel economy. So what happens if I don’t replace your O2 sensor? A broken sensor can not only affect your miles per gallon, but it can cause significant damage to your catalytic converter and your Hyundai Equus's spark plugs.

The catalytic converter's function is to turn the carbon monoxide created by the combustion process into carbon dioxide. A damaged catalytic converter is frequently caused by regularly neglected maintenance, which is why Nalley Hyundai offers a complimentary multi-point examination with every Hyundai service. If you have an issue with your catalytic converter and don't get it repaired, your Hyundai Equus will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your vehicle may run at a higher temperature, too, which can cause other perilous problems from overheating.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your Hyundai Equus if it’s not installed correctly. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even prevent the car from starting. If these issues sound familiar, bring your Equus to Hyundai and have our team of accomplished certified mechanics make sure that your aftermarket items were installed accurately and aren't causing any issue. Getting accessories, particularly aftermarket parts and accessories, or using OEM parts first place might cost a little bit more but could help you save considerably 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 Hyundai Equus 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 certain changes, like altitude. If your Hyundai Equus is having trouble starting, idling rough or has a sudden rapid change in the position of the throttle pedal, this could be a essential sign of a broken mass airflow sensor.
  • Your Hyundai Equus has a vacuum leak. Every Hyundai Equus has a vacuum system that performs a wide variety of functions. The vacuum system likewise helps lower adverse 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, particularly if they’re exposed to intense heat or extreme cold.
  • New Spark Plugs or Plug Wires are needed for your Hyundai Equus. The spark plugs are the part of your engine that ignites the air/fuel mix in the combustion chamber of your car. This explosion is what moves the pistons and makes the engine run smooth. 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 a conspicuous poor performance and decreased 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, leading to more pricey repairs.
  • One of the most common and frequent cause is that your Hyundai Equus gas cap is loose, damaged or missing. The gas cap for your Hyundai Equus serves various purposes. It prevents unpredictable 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 broken 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 and be more pricey. Luckily, to replace a gas cap isn't pricey. If your check engine light turns on expeditiously after you put gas in your Hyundai Equus, 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.
