Understanding Your Check Engine Light At Hogan Tire & Auto
If your check engine light turns on while driving, it can be a stressful experience. The check engine light is part of your vehicle’s onboard diagnostics system (OBD II) and alerts you to possible engine problems. While some issues are minor, others can affect engine performance or the emission control system, requiring immediate attention. At Hogan Tire & Auto, with eight locations across Massachusetts, our experienced technicians can diagnose and fix the problem efficiently.
Why Does The Check Engine Light Illuminate?
Your vehicle’s check engine light can turn on for many reasons, ranging from simple fixes to serious mechanical issues. Some common causes include:
- Loose gas cap – If your check engine light turns on after refueling, try tightening the gas cap. A loose cap can cause fuel vapors to escape, triggering the light.
- Faulty oxygen sensor – The oxygen sensor monitors exhaust gases and helps control fuel efficiency. A malfunctioning sensor can lead to poor gas mileage and increased emissions.
- Malfunctioning catalytic converter – The catalytic converter reduces harmful pollutants like carbon monoxide from your exhaust. If it fails, your car may not pass an emissions test.
- Issues with spark plug wires – Worn-out spark plug wires can cause misfires, reducing engine performance and fuel efficiency.
- Mass airflow sensor failure – The mass airflow sensor measures the air entering your engine to ensure proper fuel mixture. If it fails, your car might stall or hesitate while accelerating.
What To Do When The Check Engine Light Turns On
When your check engine light turns on, the first step is not to panic. If the light remains steady, it usually means a minor issue that should be checked soon. However, if you notice a flashing check engine light, this indicates a serious problem that could damage your engine.
- Check for a loose gas cap – As mentioned earlier, a loose gas cap is a common cause. Try tightening it and see if the light goes off after a few trips.
- Pay attention to other warning lights – If other dashboard lights come on, such as low oil pressure or overheating, pull over safely and seek professional help immediately.
- Observe engine performance – If you notice rough idling, stalling, or reduced power, your vehicle may have a more significant issue.
When To Seek Professional Help

- Emission system failures – Problems with the emissions system can cause increased pollutants, making your vehicle fail an emissions test.
