What could cause the check engine light to come on in a 2018 Chevy Bolt EV?

When your check engine light comes on, this could be as simple as tightening or replacing your gas cap. Likewise, the check engine light could still be a warning of a serious problem that could cause serious damage to your engine and come with a hefty and expensive repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady and continuous glow usually means something less serious but a flashing check engine light indicates that your vehicle’s engine is in meaningful trouble and useful service is needed rapidly. If your check engine light is flashing in your 2018 Chevy Bolt EV, we remarkably advise not to drive the vehicle and schedule Chevy 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 expeditiously and your vehicle will be less efficient 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 serious damage to your catalytic converter and your 2018 Chevy Bolt EV's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the exactly correct mix of air and fuel that enters the cylinders in your engine. A faulty O2 sensor can also cause a vehicle to fail an emissions test.
• Your 2018 Chevy Bolt EV has a vacuum leak. Every Chevy Bolt EV has a vacuum system that performs a wide variety of functions. The vacuum system also 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.
• Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2018 Chevy Bolt EV’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 consistently neglected maintenance, which is why Stevinson Chevrolet offers a complimentary multi-point examination with every Chevy service. If you have an issue with your catalytic converter and don't get it repaired, your 2018 Chevy Bolt EV 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 dangerous problems from overheating.
• One of the most common and frequent cause is that your 2018 Chevy Bolt EV gas cap is loose, damaged or missing. The gas cap for your 2018 Chevy Bolt EV serves different purposes. It prevents dangerous 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 faulty 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 costly. If your check engine light turns on instantly after you put gas in your 2018 Chevy Bolt EV, 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.
• The battery is low or dead. The battery in your 2018 Chevy Bolt EV is every vital. Without a vehicle battery, your vehicle won’t start, light up the road ahead, play the radio or charge your phone. Today’s vehicle batteries last much longer than they did a few decades ago, and they don't absolutely require maintenance. The price of a new one depends on the type of Chevy you drive, but check our current service coupons and specials.
• Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Chevy Bolt EV 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 Chevy Bolt EV is having trouble starting, idling rough or has a sudden speedy change in the position of the throttle pedal, this could be a important sign of a faulty mass airflow sensor.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your 2018 Chevy Bolt EV if it’s not installed perfectly. 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 familiar, bring your Bolt EV to Chevy and have our team of gifted certified mechanics guarantee that your aftermarket items were installed perfectly and aren't causing any issue. Getting accessories, particularly aftermarket parts and accessories, or utilizing OEM parts first place might cost a little bit more but could help you save substantially from having to get poor work and damage caused by poor installation work corrected.
• New Spark Plugs or Plug Wires are needed for your 2018 Chevy Bolt EV. The spark plugs are the part of your engine that ignites the air/fuel mix in the combustion chamber of your vehicle. 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 noticeable 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, leading to more costly repairs.
