Why is My Check Engine Light On?

Check Engine LightYou are driving your car down the freeway, and everything seems to be fine. Then suddenly the Check Engine Light illuminates on the dashboard. When this issue occurs, it is important that you address this problem in a timely manner.

In this blog, we will take a look at what to do when your Check Engine Light comes on, some possible reasons for it, and most importantly, how to get the problem resolved.

What is the Check Engine Light?

Today’s vehicles are extremely intricate machines, with many onboard computers controlling all the vehicle’s complex operations.

When the Check Engine Light becomes illuminated it is a warning to the driver that the car’s onboard computers have detected a problem that a system in the vehicle is not performing as it should.

Your vehicle will also tell you the severity of the situation by illuminating the Check Engine Light in several different ways.  A solid yellow light means that the issue at hand is not immediately urgent but should be addressed.

A flashing light is an indication that something is seriously wrong and requires immediate attention.

Anytime your Check Engine Light comes on it is very important to take your car to a qualified repair shop to diagnose the issue.

Top Reasons That Check Engine Lights Appear

Engine Issues

Various engine problems can trigger the Check Engine Light to come on. Whether it be low oil pressure, overheating, or drivability issues, the light is a warning that something is going on that should not be happening.

Transmission Problems

Your car’s transmission plays a critical role in its operation, as it transfers engine power to the wheels, so the vehicle can move. Some transmission issues are mechanical in nature, and others are electronic or computer related. Transmission problems may cause the Check Engine light to illuminate. 

Emission System

Today’s modern cars are equipped with sophisticated emissions systems that are designed to minimize the amount of pollution a vehicle produces while in operation.

There are many sensors and other components that make up a car’s emission system. If any component stops performing as it should, the Check Engine Light will appear.

Overheating

Engines and transmissions produce a tremendous amount of heat as they drive down the road.

A car’s cooling system is designed to keep the vehicle’s operating temperature within the proper range. When this system develops an overheating problem, serious damage to the engine can result.

How Do You Resolve a Check Engine Light Problem?

Just as cars have many sophisticated on board computers today, modern repair shops invest in complex diagnostic equipment that is used to determine what is wrong with a vehicle, and the best strategy to fix it.

Highly trained technicians connect to a car’s computer system by using diagnostic equipment at the repair shop. Based on a wide variety of trouble codes and performance measurements, a technician can interpret the nature of a vehicle’s issue and decide how to properly repair it.

Once the proper repairs have been made, the technician can “clear” the Check Engine light and turn it off. Then the technician will take a test drive and ensure all systems are operating properly.

Winterize your vehicle

If the weather turns frightful is your vehicle ready for winter driving? Stay safe & keep your vehicle in good working order this winter with the following tips:

Battery Test Check Mark Battery test-If the battery is not checked, there is a chance the particularly cold nights will be too much, making the battery unable to power on the next day.

Antifreeze Check Mark Antifreeze-Another serious issue that often comes up in the winter is lack of enough coolant, which can cause the engine to freeze and possibly crack, causing detrimental harm.

Charging Systems Check Mark Charging system check-Your charging system needs to be tested to ensure it can handle running multiple items such as your defrosters, headlights, and heater at once.

Belt and Hoses Check Mark Belt & hose inspection-Cracked or worn belts are a big reason why cars break down. Similarly, hoses need to be inspected for leaks, bulging, etc. These should be checked annually before the winter months, so there is no chance of getting stranded out in the cold unnecessarily.

Brake Check Mark Brake check-Having brakes in good condition is imperative for slippery winter roads. Having your brakes and ABS system checked each year ensures you will be able to come to a stop easily should you happen to slide.

Oil Change Check Mark Oil change-Important year-round, having your oil changed for the winter months is a step you should not forget. Be sure to refer to your car’s owner manual, as some car manufacturers suggest using a different grade of oil for colder temperatures.

Wiper Blade Check Mark New wiper blades-It is necessary to have windshield wiper blades in good condition for when you get caught driving in the snow. There are even a variety of specialty wiper blades made specifically for snowy weather.

Tire Check Mark Tire maintenance-It is of utmost importance to make sure your tire pressure is at a good level. Tires should be inspected, as well as rotated if you have not done so recently.

Other helpful tips:

  • Run your air conditioning roughly once per month. This will help decrease the time it takes your windows to defog.
  • Keep your gas tank at least half full. The added weight helps in slippery conditions, and it also helps prevent moisture from forming.
  • Do not forget to keep a snow brush/ice scraper in your car.

To Change My Oil or Not?

Regular oil changes will save you money in the long run! Most car manufacturers now recommend oil changes between 7,500 and 10,000 miles, although some specify 5,000-mile intervals. The type of engine oil, the age and make of your vehicle and driving habits dictate when to change engine oil. When in doubt check your vehicle’s owner’s manual. If you put off oil changes, it can lead to engine damage.

In addition to regular oil changes, it’s highly recommended that you change your oil filter frequently. The oil filter protections your engine from abrasive particles such as dirt and other solid contaminants. If you wait too long to change the filter it can become clogged, and then as a result unfiltered oil will be circulated through your engine and can cause easily prevented corrosion or damage to your engine.

To find out just how often you should change your oil filter, make sure you consult with your Car-X Man during your next oil change and free inspection!
