Active Fuel Management vs. Dynamic Fuel Management

When purchasing a truck or vehicle intended to tow, haul, or go off-road, the engine picked will be the engine that can successfully do the job. But what about during everyday driving? Full power from your large engine 100% can cause unnecessary wear and a loss of precious fuel economy.

That is why GM created the Active Fuel Management and Dynamic Fuel Management systems. Active Fuel Management and Dynamic Fuel Management are engine systems GM has implemented for better fuel efficiency without sacrificing horsepower or torque.

What is Active Fuel Management?

When you’re driving at cruising speeds or in conditions where your engine is not utilizing all power, the Active Fuel Management comes into play. This system detects when your engine does not need full power and will stop fuel delivery to half the cylinders, 3 on a V6 engine and 4 on a V8 engine. A solenoid system will then deactivate those cylinders to decrease power used and, according to GM authority, improve fuel economy by up to 12 percent. The Active Fuel Management system performs quietly and seamlessly so you won’t even know it’s happening.

What is Dynamic Fuel Management?

The Dynamic Fuel Management system takes a step up from Active Fuel Management and adds the advancement of technology with a DFM computer that makes quick calculations that determine how many — and which — cylinders need to be deactivated to perform at optimum levels. This sophisticated system can make this determination 80 times a second and operates with 17 different cylinder patterns (GM Authority). This technology is an industry-first and can be found in new vehicles, such as the 2021 Sierra 1500.

Both of these great technological automotive advancements have given consumers less time at the pump and more time on the road — ask our experts here at Speck Buick GMC of Tri-Cities how you can keep your big engine and save your fuel with these systems today.

Check Engine Light Diagnostic Near Kennewick, WA

Has your check engine light come on recently? Do not ignore it. A check engine light diagnostic near Kennewick, WA is the fastest and most reliable way to find out what is going on with your vehicle. At Speck Buick GMC, our certified technicians are ready to help. Here is everything you need to know about your check engine light and why a diagnostic matters. What Is the Check Engine Light? The check engine light is part of your vehicle's onboard diagnostic system. It is also known as the malfunction indicator lamp or MIL. Your vehicle's computer monitors hundreds of sensors and systems simultaneously. When something falls outside of normal operating parameters, the computer triggers the check engine light. Think of it as your vehicle's way of telling you something needs attention. It does not always mean something catastrophic is wrong. However, it should never be ignored. Common Causes of the Check Engine Light The check engine light can come on for many different reasons. Some causes are minor and inexpensive to fix. Others can be more serious if left unaddressed. Here are some of the most common reasons your check engine light may be on: Loose or Damaged Gas Cap A loose, cracked, or missing gas cap is one of the most common triggers for the check engine light. It causes fuel vapors to escape from the fuel system. Simply tightening or replacing your gas cap may resolve the issue. It is always worth checking your gas cap first before assuming a bigger problem exists. Oxygen Sensor Failure Your oxygen sensor monitors the amount of unburned oxygen in your exhaust system. A failing oxygen sensor can affect fuel economy and engine performance significantly. It is one of the most commonly replaced components after a check engine light diagnostic. Ignoring a faulty oxygen sensor can lead to damage to your catalytic converter over time. Catalytic Converter Issues Your catalytic converter reduces harmful emissions from your exhaust system. A failing catalytic converter can cause reduced engine performance and poor fuel economy. It is often triggered by ignoring other warning signs like a faulty oxygen sensor. Catalytic converter replacement is one of the more costly engine repairs available. Mass Airflow Sensor Failure The mass airflow sensor measures the amount of air entering your engine. A failing sensor disrupts the air and fuel mixture your engine needs to run properly. Symptoms include rough idling, poor acceleration, and reduced fuel economy. A check engine light diagnostic can quickly identify a faulty mass airflow sensor. Spark Plug or Ignition Coil Issues Worn spark plugs or failing ignition coils are a common cause of engine misfires. Misfires trigger the check engine light and can cause rough idling and poor acceleration. They can also cause long-term damage to your catalytic converter if left unaddressed. Regular spark plug replacement is an important part of routine engine service. Thermostat Issues A failing thermostat can cause your engine to run too hot or too cold. Both conditions can trigger the check engine light and affect engine performance. A faulty thermostat can lead to serious engine damage if not addressed quickly. Our engine service team can diagnose and replace a faulty thermostat quickly and efficiently. EVAP System Leaks The evaporative emission control system prevents fuel vapors from escaping into the atmosphere. A leak in the EVAP system is a common cause of the check engine light. EVAP leaks can range from a simple loose gas cap to a more complex system failure. A professional check engine light diagnostic is the best way to identify the exact source of an EVAP leak. Why Is It Important to Get a Diagnostic Done? Getting a check engine light diagnostic done promptly is one of the most important things you can do as a vehicle owner. Here is why: A diagnostic gives you accurate information about what is going on with your vehicle. It removes all of the guesswork and points directly to the source of the problem. Without a diagnostic, you are essentially guessing at what might be wrong. That can lead to unnecessary repairs and wasted money. Our Service Advisor Dani puts it best: "Even if you think you know what the problem is, there could be a bigger underlying problem." — Dani, Service Advisor, Speck Buick GMC This is advice worth taking seriously. What appears to be a minor issue on the surface can sometimes point to a much larger problem underneath. A professional engine diagnostic gives you the full picture before any repair work begins. It protects you from spending money on the wrong fix. A diagnostic also helps prevent small problems from becoming big ones. Catching an issue early almost always means a less expensive repair. Ignoring the check engine light and hoping it goes away is never a good strategy. The longer you wait, the more damage can occur. What Happens During a Check Engine Light Diagnostic? Our certified technicians connect a professional-grade diagnostic scanner to your vehicle's OBD-II port. The scanner reads the fault codes stored in your vehicle's computer. Those codes tell us exactly which system or component triggered the check engine light. Our technicians then perform a thorough inspection to confirm the root cause of the problem. You receive a clear explanation of what was found and what repair is recommended. There are no surprises and no pressure.
