Even if your vehicle seems to be driving normally, the warning light means something needs attention.

Frequently Asked Questions (FAQ)
Can I drive with my check engine light on?
If the light is solid, limited driving may be okay for a short time, but diagnostics should be scheduled as soon as possible. If the light is flashing, stop driving immediately.
Is a check engine light always expensive to fix?
No. Many causes are minor and affordable when caught early. Ignoring the light often leads to higher repair costs later.
Will the check engine light turn off by itself?
Sometimes it may turn off temporarily, but that doesn’t mean the issue is resolved. The problem can return and worsen over time.
Do you diagnose all makes and models?
Yes. Lighthouse Automotive services most domestic and import vehicles using professional diagnostic equipment.
Does a loose gas cap really cause the check engine light?
Yes, it’s one of the most common causes. However, if tightening it doesn’t turn the light off after a few drive cycles, diagnostics are needed.
How long does a diagnostic take?
In most cases, diagnostics can be completed the same day. More complex issues may require additional testing.
