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

When your check engine light comes on, this could be as plain as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a stringent problem that could cause stringent damage to your engine and come with a extensive repair bill. Depending on your make and model, the check engine light will illuminate or blink. A dependable glow typically means something less stringent but a flashing check engine light suggests that your vehicle’s engine is in stringent trouble and service is crucial abruptly. If your check engine light is flashing in your Chevy, we highly endorse not to drive the vehicle and schedule Chevy service abruptly. Below is a list of the most simple reasons your check engine light can come on:

• The battery is scanty or dead. The battery in your Chevy is every splendid. 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 Chevy you drive, but check our contemporary service coupons and specials.
• 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 vehicle will be less direct 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 Chevy '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.
• Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Chevy 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 actual changes, like altitude. If your Chevy 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.
• Your Chevy has a vacuum leak. Every Chevy has a vacuum system that performs a wide variety of functions. The vacuum system also helps lessen 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, especially if they’re exposed to exciting heat or extreme bitter.
• One of the most acceptable and plentiful cause is that your Chevy gas cap is loose, damaged or missing. The gas cap for your Chevy 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 aged 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 hastily after you put gas in your Chevy, 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.
• New Spark Plugs or Plug Wires are needed for your Chevy. 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 aged, 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, extensive to more expensive repairs.
• Your catalytic converter is bad or going bad. The catalytic converter is a part of your Chevy ’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 Chevrolet at the Avenues offers a complimentary multi-point inspection with every Chevy service. If you have an issue with your catalytic converter and don't get it repaired, your Chevy 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 additional problems from overheating.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or additional item can wreak havoc on your Chevy if it’s not installed accurately. 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 prevailing, bring your to Chevy 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.
