As a staple in different Chevrolet and GMC vehicles, Duramax engines are a reliable series of turbo-diesel powerhouses. Initially introduced in 2001, the Duramax engine has undergone several redesigns to today’s present model. While each iteration has improved and gained more functionality, they all operate at the behest of an onboard computer, which continually scans and monitors the vehicle.
If the onboard computer detects something awry, it will trigger the Check Engine Light on the Duramax diesel. The Check Engine Light on Duramax diesel trucks is the telltale sign that your vehicle needs attention. The underlying issue can range from minor to more serious auto repairs. Let’s take a closer look at the Check Engine Light on Duramax diesel trucks, what it may mean, and how the team at Branch Automotive in Littleton CO can help.
A Loose Gas Cap Can Trigger the Check Engine Light on Duramax Diesel Trucks in Littleton CO
Most — if not all — drivers are pleasantly surprised to learn one of the most common causes of the Check Engine light is a loose gas cap. When tightly secured, your gas cap creates a vacuum within the tank and prevents gas vapors from escaping. Anytime your gas cap is off, it can cause a vapor leak, which the onboard computer system will detect. When it does, it will trigger the Check Engine Light on Duramax diesel trucks in Littleton CO. Because of this, of your Check Engine Light is illuminated in Littleton CO, the first step should be to inspect whether your gas cap is on and tightened.
Oxygen Sensors Can Cause the Check Engine Light on Duramax Diesel Trucks to Illuminate in Littleton CO
If your oxygen sensor is failing on your truck, it can trigger the Check Engine Light. A faulty or poorly performing oxygen sensor will lose the ability to measure the amount of oxygen in your exhaust. When this occurs, it may no longer add the right amount of fuel to your engine. For the most part, this diesel repair is inexpensive. However, ignoring the issue can cause your engine to work much harder, reduce fuel efficiency, and lead to expensive repairs.
Your Check Engine Light Can Be Triggered by a Bad Catalytic Converter in Littleton CO
Your catalytic converter is a part of your diesel exhaust system. It’s designed to morph carbon monoxide created during the combustion process into carbon dioxide. You can protect and prolong your catalytic converter by having regular maintenance — such as oil changes —as suggested by the manufacturer. Also, keep your eyes and ears open for discolored exhaust smoke or for unusual sounds. In either case, if your catalytic converter is failing or malfunctioning, it may trigger the Check Engine Light on Duramax diesel trucks in Littleton CO.
Bad Glow Plugs Can Cause Your Check Engine Light to Come On
While gasoline vehicles have spark plugs, your diesel Duramax truck has glow plugs. Like spark plugs, glow plugs are heating elements that heat the incoming air and fuel to promote efficient combustion in the diesel engine. If your glow plugs fail, they can throw your truck’s emissions out of whack. At the same time, it can cause your engine computer to trigger the Check Engine Light in Littleton CO.
A Leaky Vacuum Hose Can Cause Your Check Engine Light to Illuminate in Littleton CO
Another common cause of an illuminated Check Engine Light are leaky vacuum hoses. If you have a leak or hole in your vacuum hose, it can cause your valuable diesel to evaporate prior to it reaching the right destination. When you have a leaky vacuum hose, it can trigger the Check Engine Light on Duramax diesel trucks.
