LEARN ABOUT YOUR CHECK ENGINE LIGHT
Why this little icon is the most important part of your dash
Whenever you start your vehicle, you may notice several icons on your dash panel, including your check engine light, come on for a moment. This is normal, as it usually means that your vehicle is testing the circuits for each of these indicators. The problem occurs when one or more of the lights stays on after this process is complete.
Wondering what your check engine light means? While this warning light can indicate a variety of problems, an experienced auto service technician can usually figure it out fairly quickly. When you come to us with a glowing or flashing check engine light, our team members will conduct a series of diagnostic tests to help us understand what’s going on with your vehicle. Then, we’ll come up with some suggested next steps to help you solve the problem as efficiently and affordably as possible—with the highest-quality service and parts.

WHY IS YOUR CHECK ENGINE LIGHT ON?
If your check engine light flashes on your dash panel, this usually means there is a serious problem with one or more parts of your engine. Some common reasons include:
Here are some of the most common symptoms that you have a faulty transfer case:
- Sensor Failure
These sensors help maintain your vehicle’s safety and efficiency by monitoring things like exhaust, emissions, and air flow. When the sensors go bad, the check engine light may be the only obvious sign, which is why it’s important to get that checked out right away. - Loose/Damaged Fuel Cap
This problem could be a simple fix: just tighten your gas cap and reset the engine light. If the light comes back on, you know that there is either additional damage to the cap or some other engine-related problem. - EGR Valve/Catalytic Converter Issue
Similar to the previous problems, the EGR valve and catalytic converter helps reduce harmful emissions released by the operation of your vehicle. Failure to repair or replace these parts can cause serious environmental and health hazards. - Spark Plug/Battery Issue
Since these parts keep the rest of your vehicle going strong, it’s important to replace them whenever necessary. Your mechanic can determine if this is the reason your check engine light is on. - Vacuum Leak
While this issue is not always dangerous, it can significantly affect your vehicle’s power and fuel efficiency. Other than the engine light, there may be no apparent sign of this problem.
If your check engine light is blinking, this is usually a sign that your engine is misfiring. This means that unburned fuel is likely moving into your exhaust system. This is a serious issue that should be addressed right away. Be sure to contact your service provider for more information.

THE BENEFITS OF CHECK ENGINE LIGHT REPAIRS
IMPROVED SAFETY – Many engine problems can cause dangerous issues with your vehicle—or be dangerous on their own. That’s why it’s crucial that you seek professional service as soon as your check engine light comes on, especially if it’s flashing.
HEALTHIER PLANET-Many of the issues that trigger your check engine light to come on indicate a problem with the sensors or seals that control the emissions caused by your vehicle. A malfunction in any of these areas can do serious damage to the environment.
BETTER EFFICIENCY – Among other things, issues with your spark plugs, battery, and vacuum seals can also affect the fuel efficiency and power of your vehicle. These problems are not always obviously apparent, so the check engine light is a powerful tool to alert the vehicle owner of the problem.
HOW TO PREVENT PROBLEMS WITH YOUR ENGINE
Once you get your engine back online, you can keep everything running smoothly by:
Inspecting
Every month, you should be sure to check your oil, interior lights, exterior lamps, turn signals, and tires for optimal performance. Your owner’s manual may have other suggestions on what to inspect, and when. You can perform these yourself, or seek out a trusted service provider to do it for you.
Maintaining
Performing prompt and proper maintenance on your vehicle is crucial to prolonging the life of your vehicle. Check your owner’s manual to see when maintenance should be performed and when certain parts should be replaced. Following this schedule can prevent unnecessary, expensive repairs.
Trusting
Finding a trustworthy, reliable mechanic is the first and most important step for any vehicle owner. That way, you never have to deal with searching for a service provider after things have already gone wrong.
