Why is my check engine light flashing and car shaking on my Toyota Corolla?
Seeing your check engine light flashing while your Toyota Corolla shakes can be alarming. These symptoms often indicate a serious issue that requires immediate attention. As an experienced auto service provider, I’ll walk you through the potential causes and what steps you should take to address the problem.
What Does a Flashing Check Engine Light Mean?
A flashing check engine light is different from a steady one. While a steady light signals a less urgent issue, a flashing light typically indicates a severe problem, such as an engine misfire. Ignoring this warning can lead to significant engine damage or even complete failure.
Why Is Your Toyota Corolla Shaking?
The shaking you’re experiencing is often related to the same issue causing the flashing check engine light. Here are some common reasons:
- Engine Misfire: A misfire occurs when one or more cylinders in your engine fail to ignite properly. This can cause the engine to run unevenly, leading to shaking.
- Faulty Spark Plugs or Ignition Coils: Worn-out spark plugs or failing ignition coils can disrupt the combustion process, resulting in misfires and vibrations.
- Fuel Delivery Issues: Problems with the fuel injectors or fuel pump can cause an uneven fuel supply, leading to engine misfires and shaking.
- Vacuum Leaks: A vacuum leak can disrupt the air-fuel mixture in your engine, causing rough idling and shaking.
- Clogged Catalytic Converter: A clogged catalytic converter can restrict exhaust flow, leading to engine performance issues and vibrations.
Steps to Take Immediately
If your check engine light is flashing and your car is shaking, follow these steps to prevent further damage:
- Pull Over Safely: Stop driving as soon as it is safe to do so. Continuing to drive can worsen the issue and lead to costly repairs.
- Check for Obvious Issues: Look under the hood for any visible problems, such as loose wires or disconnected hoses. However, avoid touching anything if you’re unsure.
- Scan for Error Codes: Use an OBD-II scanner to retrieve the error codes from your car’s computer. These codes can help pinpoint the issue.
- Call a Professional: Contact a trusted auto repair shop, like Kevin’s Autos, to diagnose and fix the problem. Driving with a flashing check engine light can cause severe engine damage.
