Why Car Diagnostics Are So Important
In the past, diagnosing car problems often meant guesswork. Today, with advanced technology, professional car diagnostic testing pinpoints the exact issue quickly and accurately. This saves you time, money, and frustration by eliminating unnecessary repairs.
At Japanese Automotive, our diagnostic process gives you clear answers so you can make informed decisions about your car repair. We don’t just clear codes—we find out why the issue happened and fix it right the first time.
Common Reasons the Check Engine Light Comes On
Your check engine light is one of the most common signs that your car needs diagnostics. Here are some issues it may indicate:
- Loose or damaged gas cap – A simple issue that can affect fuel efficiency.
- Oxygen sensor failure – Impacts emissions and fuel economy.
- Catalytic converter problems – Can cause poor performance or emissions issues.
- Spark plug or ignition coil failure – Leads to misfires and rough driving.
- Mass airflow sensor issues – Affects engine power and fuel use.
- Transmission-related codes – May signal slipping or shifting issues.
Because the check engine light can mean many different things, only professional diagnostic testing can determine the exact cause.

What does the check engine light mean?
It can mean many things—from a loose gas cap to serious engine problems. Car diagnostic testing is the only way to know for sure.

It depends. If the light is steady, you may still drive short distances. If it’s flashing, stop immediately and schedule service—it signals a serious problem.
How long does diagnostic testing take?
Basic testing may take less than an hour. More complex issues that require further inspection can take longer.

Whenever your check engine light comes on, or if you notice performance issues. Routine diagnostics during maintenance visits are also a smart idea.
