Check Engine Light Service 2020 Chevy Express 2500

What do you do when you’re driving along in your Chevy Express 2500 and suddenly, a yellow light illuminates on your dash and says "Check Engine". If you’re like most Chevy owners, your heart sinks exceptionally because you may have definitely idea about what that light is trying to tell you or how you should react. The fear of the unknown (or the cost of the unknown) can be just as stressful. But take a deep, calm breath and realize the light coming on doesn’t mean you have to pull the car over to the side of the road and call a tow truck, but it is advised that you get your 2020 Chevy Express 2500 checked instantly. Ignoring that warning could end up causing major, major damage to pricey engine components.

When your 2020 Chevy Express 2500's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electronic control system that it can’t correct, a computer turns on your check engine light. This amber or yellow light is generally labeled “check engine” or “service engine soon”, or the light may be nothing more than a picture of an engine, or a picture of the engine with the word “check.”

When the light turns on, the ECM stores an engine code or “trouble code” in its memory that can rapidly identify the issue, whether it's a sensor or a failing engine part. This code is read with an electronic scan tool that is used by our Chevy auto repair mechanics at Stevinson Chevrolet. There are likewise a number of relatively inexpensive code readers that are designed for do-it-yourselfers, should you select that route too. While this code will tell you the issue that is detected, a true diagnosis still requires an experienced professional to determine the precisely correct issue and repair it.

What could cause the check engine light to come on in a 2020 Chevy Express 2500?

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 also be a warning of a meaningful problem that could cause serious damage to your engine and come with a hefty and pricey 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 serious trouble and useful service is needed immediately. If your check engine light is flashing in your 2020 Chevy Express 2500, we highly propose not to drive the car and schedule Chevy service today. Below is a list of the most common reasons your check engine light can come on:

• New Spark Plugs or Plug Wires are required for your 2020 Chevy Express 2500. 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 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.
• Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2020 Chevy Express 2500’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 regularly 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 2020 Chevy Express 2500 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.
• The battery is low or dead. The battery in your 2020 Chevy Express 2500 is every crucial. Without a vehicle battery, your vehicle won’t start, light up the road in front, 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 really 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 Express 2500 is what determines how much fuel is required 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 Express 2500 is having trouble starting, idling rough or has a sudden rapid change in the position of the throttle pedal, this could be a critical sign of a faulty mass airflow sensor.
• 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 rapidly 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 faulty sensor can not only affect your miles per gallon, but it can cause serious damage to your catalytic converter and your 2020 Chevy Express 2500's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the absolutely correct mixture 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 2020 Chevy Express 2500 has a vacuum leak. Every Chevy Express 2500 has a vacuum system that performs a wide 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, particularly if they’re exposed to intense heat or extreme cold.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your 2020 Chevy Express 2500 if it’s not installed properly. These aftermarket components 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 Express 2500 to Chevy and have our team of talented certified mechanics ensure that your aftermarket items were installed accurately and aren't causing any issue. Getting accessories, particularly aftermarket parts and accessories, or using OEM components 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.
• One of the most common and frequent cause is that your 2020 Chevy Express 2500 gas cap is loose, damaged or missing. The gas cap for your 2020 Chevy Express 2500 serves different purposes. It prevents perilous 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 costly. Luckily, to replace a gas cap isn't pricey. If your check engine light turns on instantly after you put gas in your 2020 Chevy Express 2500, 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.

Will the check engine light reset itself?

The check engine light on your 2020 Chevy Express 2500 will frequently shut itself off if the issue or code that caused it to turn on is fixed. For instance, if the cause of your check engine light coming on was a loose gas cap, if it's tightened, the light will instantly turn itself off. Again, if your catalytic converter is working correctly, 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 2020 Chevy Express 2500 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 Stevinson Chevrolet so the light and code can be double-checked and reset.
