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

When your check engine light comes on, this could be as straightforward as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a risky problem that could cause risky damage to your engine and come with a generous repair bill. Depending on your make and model, the check engine light will illuminate or blink. A consistent glow frequently means something fewer risky but a twinkling check engine light indicates that your vehicle’s engine is in risky trouble and service is paramount at this moment. If your check engine light is twinkling in your Chevrolet, we exceedingly advise not to drive the vehicle and schedule Chevrolet service today. Below is a list of the most known reasons your check engine light can come on:

  • Your O2 Sensor (Oxygen Sensor) needs to be replenished. The Oxygen sensor, acknowledged as the O2 sensor, measures the deposit of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less convenient 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 Chevrolet 's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to express 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.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your Chevrolet ’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 Nalley Chevrolet offers a complimentary multi-point inspection with every Chevrolet service. If you have an issue with your catalytic converter and don't get it fixed, your Chevrolet 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.
  • Your Chevrolet has a vacuum leak. Every Chevrolet has a vacuum system that performs a giant 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 imposing heat or extreme cold.
  • The battery is low or dead. The battery in your Chevrolet is every basic. 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 altogether require maintenance. The rate of a new one depends on the type of Chevrolet you drive, but check our regular service coupons and specials.
  • One of the most regular and frequent cause is that your Chevrolet gas cap is loose, damaged or missing. The gas cap for your Chevrolet 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 former 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 expeditiously after you put gas in your Chevrolet, first thing you should check is to make hopeful the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • Your mass airflow sensor (known as MAF) needs to be replenished. The mass airflow sensor in your Chevrolet is what determines how much fuel is needed to run your engine efficiently by measuring the deposit of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to excellent changes, like altitude. If your Chevrolet is having trouble starting, idling rough or has a hasty change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or extra item can wreak havoc on your Chevrolet if it’s not installed properly. These aftermarket parts and accessories can eject the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound conscious, bring your to Chevrolet and have our team of certified mechanics ensure that your aftermarket items were installed accurately 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 work and damage caused by poor installation work corrected.
  • New Spark Plugs or Plug Wires are needed for your Chevrolet. 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 transport the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are bad or former, 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, dominant to more expensive repairs.

How many miles can you drive with the check engine light?

Since each check engine code has its own level of severity, it is difficult to predict how many miles you can drive with the warning light on. The safest bet is to decipher the code and then plan your strategy accordingly. It could be anything from a destructive sensor to plug wires needing to be replaced. If you check engine light is blinking, we recommend that you pull over and contact Nalley Chevrolet to help opt for if your vehicle is safe to drive in or if we recommend a tow truck.

Will the check engine light reset itself?

The check engine light on your Chevrolet will ordinarily 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 careful, 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 Chevrolet light will go off after about 20-40 miles. If you drive over that amount and the light is still on, you will need to bring it in to Nalley Chevrolet so the light and code can be double-checked and reset.
