Common Reasons the Check Engine Light Comes On


When your check engine light comes on, it doesn't necessarily mean that your engine is on the cusp of failure. But it's definitely best to visit the shop for computerized diagnostics so that any emerging issues can be identified before they escalate and become more expensive to fix. At Powerhouse Auto Repair, our local mechanics can accurately diagnose your engine trouble. Then we'll get right to work on addressing the issue so you can get back behind the wheel ASAP.

Why is my check engine light on?

Issues with the catalytic converter are often why the check engine light illuminates. It's important to promptly take care of catalytic converter problems so that you're not driving a vehicle that is excessively polluting. Signs of a faulty catalytic converter include worsening acceleration, a sulphurous odor, and decreasing fuel-efficiency. With a malfunctioning oxygen sensor, your check engine light may illuminate and trouble with your catalytic converter could develop. The mass airflow sensor is another sensor that---when there's trouble with it---can cause the light to come on. If your engine hiccups or struggles to start, then you may be dealing with a MAF sensor issue.

Faulty spark plugs are another problem that can trigger the light. Vehicles manufactured in the past two decades can commonly make it 100,000 miles before their plugs need to be replaced. Older cars tend to need new plugs more frequently. Ignition coils could also be to blame for an illuminated check engine light. With ignition coil trouble, you may notice misfiring and rough idling. Another possibility to consider is that you have a bad battery that is causing low voltage at the computer, which could in turn cause the light to come on. And in some cases, the check engine light can even be triggered by a loose gas cap. When a gas cap isn't tightly secured, gas may evaporate before your engine gets the opportunity to run on it.
