January 26, 2024
Welcome to East Rock Auto Repair Inc, your trusted auto shop in New Haven, CT. We understand that the dreaded check engine light can be a cause for concern, but fear not! In this comprehensive guide, we will unravel the mysteries of the check engine light, explain what it means, and provide you with actionable steps to take when it illuminates on your dashboard. So, let's dive in and shed some light on this warning indicator.
East Rock Auto Repair Inc, your dependable partner in auto care in New Haven, CT, is here to assist you in understanding and addressing the check engine light effectively.
What Is the Check Engine Light?
The check engine light, also known as the malfunction indicator lamp (MIL), is a small illuminated symbol on your car's dashboard. It looks like a small engine or reads "Check Engine" and is often colored orange or red. When this light turns on, it's your vehicle's way of communicating that something may not be functioning as it should within your engine or emissions system.
While it's tempting to ignore this little warning, doing so can lead to more extensive and expensive problems down the road. Therefore, it's crucial to take it seriously and address it promptly.
Common Reasons for the Check Engine Light to Illuminate
Several issues can trigger the check engine light. These range from minor concerns to potentially significant problems. Here are some of the most common reasons:
- Loose Gas Cap: Believe it or not, something as simple as a loose or damaged gas cap can trigger the check engine light. This issue is easy to fix and doesn't require professional assistance.
- Faulty Oxygen Sensor: Oxygen sensors monitor the oxygen levels in your exhaust gases and help your car's computer regulate fuel delivery. When an oxygen sensor fails, it can lead to decreased fuel efficiency and increased emissions.
- Catalytic Converter Problems: A malfunctioning catalytic converter can lead to a decrease in your vehicle's performance and increased emissions.
- Mass Airflow Sensor Issues: The mass airflow sensor measures the amount of air entering the engine, helping determine the appropriate amount of fuel needed for combustion. A faulty sensor can lead to poor performance and decreased fuel efficiency.
- Spark Plug or Ignition Coil Problems: Misfiring spark plugs or faulty ignition coils can result in reduced engine performance and should be addressed promptly to prevent further damage.
- Exhaust Gas Recirculation (EGR) Valve Malfunction: The EGR valve recirculates a portion of exhaust gases to reduce emissions. When it malfunctions, it can lead to poor fuel economy and increased emissions.
- Transmission Issues: Problems within the transmission system can trigger the check engine light. These issues can range from minor solenoid problems to more significant transmission troubles.
What to Do When the Check Engine Light Comes On
When the check engine light illuminates on your dashboard, here are the steps you should take:
- Check the Gas Cap: Start with the simplest solution by checking your gas cap. Ensure it is tight and free from damage.
- Monitor Your Vehicle's Behavior: Pay attention to your car's performance. If it's running rough, making strange noises, or experiencing a decrease in fuel efficiency, it's essential to have it inspected promptly.
- Use a Diagnostic Tool: Many auto parts stores offer free check engine light diagnostic services. They can plug a diagnostic tool into your vehicle's onboard computer system to retrieve error codes, giving you more insight into the issue.
- Seek Professional Help: If the check engine light persists or your vehicle's performance is noticeably affected, it's time to consult a professional auto technician. At East Rock Auto Repair Inc, we have the expertise and state-of-the-art equipment to diagnose and resolve the problem efficiently.

Welcome to East Rock Auto Repair's latest blog post! We're nestled in the heart of New Haven, CT, and we're here not just to offer top-notch auto services but also to empower our community with knowledge that can make car ownership a less daunting and more rewarding experience. Today, we're diving into a topic that's perfect for all the car enthusiasts out there and even those of you in New Haven and beyond who've never popped the hood. We're talking about DIY car maintenance – yes, those tasks you can tackle yourself, without needing to swing by East Rock Auto Repair every time. But remember, we’re always here when you need professional help or advice! 1. Changing Your Oil and Oil Filter Oil is the lifeblood of your vehicle; it keeps your engine running smoothly and efficiently. Changing your oil and oil filter is a quintessential task that can extend the life of your car and enhance its performance. While this might sound like a mechanic-only job, it's surprisingly doable with the right tools and a bit of patience. Start by ensuring your vehicle is on level ground and the engine is cool. You’ll need a wrench to remove the oil drain plug, an oil filter wrench, a funnel, new oil, and a new oil filter – all of which you can find at any local auto parts store in New Haven or your preferred shopping spot. Remember to dispose of the old oil responsibly; East Rock Auto Repair and other local facilities can help with that. 2. Replacing Windshield Wipers Visibility is key to safe driving, and your windshield wipers play a huge role in this, especially during New Haven’s unpredictable weather. Thankfully, replacing them is straightforward and inexpensive. Most wiper blades snap off with a little pressure and can be replaced by sliding the new ones in place until they click. This small change can drastically improve your driving visibility during rain or snow. 3. Checking and Replacing Air Filters Your car’s air filter prevents dirt and debris from entering the engine and ensures only clean air is used for combustion. A clogged air filter can decrease your car’s efficiency and performance. Checking and replacing your air filter is a quick, easy task you can do right in your driveway or garage. Typically, you just need to remove a few clips or screws from the air filter box, swap out the old filter for a new one, and you’re good to go. This task is as simple as changing a home AC filter and just as important for your vehicle's health. 4. Maintaining Tire Pressure and Treads Proper tire maintenance is crucial for safe driving and can even improve your vehicle’s fuel efficiency. Check your tire pressure monthly with a tire pressure gauge – these are inexpensive and easy to use. Compare the pressure to the recommended level found in your car’s manual or on the inside of the driver’s side door. Adjust as necessary using an air compressor at any New Haven gas station. Don't forget to check your tire treads to ensure they’re not too worn. You can do this with the penny test: insert a penny into the tread with Lincoln’s head upside down. If you can see all of Lincoln's head, it's time for new tires. If you’re unsure, pop by East Rock Auto Repair, and we can check for you. 5. Replacing Headlights and Tail Lights A burnt-out light can be a safety hazard and could lead to a ticket. Fortunately, replacing headlights and tail lights is generally a simple process that requires minimal tools. The most important part is purchasing the correct bulb for your vehicle model – this is where your vehicle’s manual comes in handy, or a quick visit to a New Haven auto parts store. Once you have the right bulb, it’s typically as easy as accessing the light housing from the back of the unit, removing the old bulb, and screwing in the new one.
