Check Engine Light Diagnostics

What to Do When You Notice Your Check Engine Light

The check engine light is also known as a malfunction indicator lamp. It’s connected to your car’s built-in diagnostics system. When the computer detects a potential issue with the engine, transmission, or emissions system, it turns the light on.

Don’t panic when you see your check engine light. The first thing to do is to identify its state.

• Is the light solid? If yes, then you have time to safely drive your car home and book a check engine light diagnostic in Farmingville, NY. The solid light hints that there’s a problem, but it isn’t yet significant.
• Is the light flashing? If yes, then the problem is more serious, and you should stop your vehicle as soon as possible before booking a tow. The flashing light is a rarer problem that occurs when there is a serious mechanical fault.

What Causes the Check Engine Light to Turn On?

While the list of potential problems is extensive, there are some fairly common issues that trigger the check engine light. One of the simplest is a loose or faulty gas cap. Others include:

• Faulty oxygen sensor that controls the air-fuel mixture.
• Malfunctioning mass airflow sensor that controls the air entering the engine. This can affect fuel economy and power delivery.
• Worn out spark plugs.
• Catalytic converter problems (usually displaying a flashing light).
• Vacuum leaks.
• Exhaust gas recirculation valve faults, affecting emissions and performance.
• Battery system problems.

These are just examples of what our team might discover during a vehicle diagnostics check. Whatever the underlying cause of your check engine light, you can trust our Farmingville check engine light diagnostic process.

5 Key Steps for Full Car Diagnostics in Farmingville

Our process ensures that you get the correct diagnostic and a cost-efficient repair. You might have noticed that some shops on Long Island offer error code readouts without any engine diagnostic cost. This type of service only tells you the codes, without looking deeper for a fault or malfunction.

Our process is much more in-depth.

1. We begin by asking you questions about your car and any odd behavior or problems that you might have noticed in recent days and weeks.
2. We retrieve the diagnostic trouble codes from your car using an advanced OBD-II scanner.
3. Trouble codes suggest problems but aren’t an actual diagnosis. We use the codes to start our own full car diagnostics. We analyze sensor data and perform physical checks to pinpoint the problem.
4. Once we find a potential issue, we will confirm it and include the exact diagnosis in a detailed report.
5. We provide you with the report and OBD-II readout and recommend a repair with a quote. We won’t start any work until you give us the go ahead.
