The check engine light is never a good sign, but it doesn’t always mean disaster. Sometimes, it’s something simple. Other times, it’s a warning that something bigger is happening under the hood. Either way, ignoring it isn’t a good idea.
At VLG Auto Service, we provide professional check engine light diagnostics in Erie, PA to find out exactly what’s going on. No guessing. No unnecessary repairs. Just a clear diagnosis and expert solutions to get you back on the road quickly.
There are many reasons why your check engine light might show up. Some are minor, others need immediate attention. Here are some of the most common check engine light causes:
Loose or broken gas cap – A faulty gas cap can cause fuel system errors and trigger the check engine light.
Faulty oxygen sensor – A failing oxygen sensor can reduce fuel efficiency and increase emissions.
Bad spark plugs – Worn-out spark plugs lead to engine misfires and rough idling.
Catalytic converter failure – If your catalytic converter is clogged, your car won’t pass an emissions test and may lose power.
Mass airflow sensor issues – A faulty mass airflow sensor affects fuel delivery and engine performance, leading to stalling.
If your check engine light is flashing, that’s a serious warning. A flashing light means your engine is at risk of severe damage, and you should get it checked immediately.
