Why this matters
A flashing light usually means a misfire that can damage the catalytic converter—an expensive part. A steady light may be minor, but it also masks new faults until it is resolved.

Scan and record all codes and data
- 2
Test the most likely cause instead of assuming
- 3
Explain urgency: drive now, repair soon, or repair today

Check Engine Light Diagnostics — questions we hear often
Can I still drive with the light on?
If it is steady and the vehicle drives normally, usually for a short time. If it is flashing, or you notice shaking or power loss, stop driving and call us at 416-642-2838.
Is it just the gas cap?
Sometimes a loose cap causes an evaporative code, but many other faults trigger the same system. Testing confirms it.
Does the check engine light affect a safety inspection?
An Ontario safety inspection focuses on safety-related items, but active faults affecting lighting or braking systems do matter. We will tell you where you stand.
