What is triggering my check engine light?

When the check engine light turns on, it doesn't necessarily indicate that your engine is about to fail. Nonetheless, you'll want to visit the shop so that diagnostics can be conducted and the issue can be pinpointed. By being proactive about solving the problem, there's a much better chance that it can be addressed before it escalates and requires very expensive engine repairs. At Austin Auto Repair, our local mechanics use advanced diagnostic technology to accurately identify engine problems when the check engine light turns on. No matter the problem that is triggering the light, we'll work efficiently to fix it and get your car back to you as quickly as possible.

Common Check Engine Light Triggers

One common issue that triggers the check engine light is a faulty catalytic converter. It's important that your catalytic converter is healthy so that your car's polluting emissions are kept to a minimum. Indications of catalytic converter trouble include dark exhaust smoke, worsening gas mileage, and a sulphurous odor. Oxygen sensor trouble can also trigger the check engine light, and potentially cause issues with your catalytic converter. Another reason the check engine light could come on is that you have a failing mass air flow sensor. A bad MAF sensor can cause herky-jerky acceleration, and may cause your engine to stall shortly after you fire it up.

A bad ignition coil is another issue that could cause the check engine light to come on. It's important that your ignition coils are healthy so that the spark is generated that your engine needs to get started. Ignition coils should work reliably for around 100,000 miles. Faulty spark plugs are a similar problem that can cause the check engine light to illuminate. Also, a bad battery can cause low voltage at the computer, which can consequently cause the check engine light to come on. And though it might seem bizarre, your check engine light might turn on if your gas cap is loose or missing.
