Frequently Asked Questions

What does the check engine light mean?
The check engine light indicates an emissions system problem. It could be something minor like a loose gas cap or something serious like a faulty sensor. We diagnose with computer scanning.
Is it safe to drive with the check engine light on?
It depends on the issue. If the light is steady, you can usually drive safely but should have it checked soon. If it's flashing, stop driving immediately—serious engine damage could occur.
How much does check engine light diagnosis cost?
We offer free check engine light scanning to identify the problem. Repair costs depend on the issue—from $50 for a loose cap to $500+ for sensor replacement.
Can I clear the check engine light myself?
You can clear it temporarily, but it will return if the underlying problem isn't fixed. We diagnose and fix the root cause to prevent it from coming back.
