Frequently Asked Questions about Check Engine Light Diagnosis in Seattle

How much does a check engine light diagnostic cost in Seattle?
Many shops in Seattle offer free OBD-II code scanning; a full diagnostic to identify the root cause typically costs $75–$150. Some shops waive the diagnostic fee if you proceed with the repair.
Is it safe to drive with the check engine light on in Seattle?
It depends on the code. A steady light is usually not an emergency, but don't ignore it for more than a week. A flashing check engine light signals an active misfire that can damage your catalytic converter — pull over safely and call a shop.
Can I reset the check engine light myself?
You can clear codes with an OBD-II scanner, but the light will return if the underlying problem isn't fixed. Address the root cause first — a shop can identify it properly and let you know what's actually wrong.
What are the most common check engine light causes?
Common culprits include a loose or failing gas cap, an oxygen sensor, catalytic converter issues, spark plugs, a mass airflow sensor, or an EVAP leak. A diagnostic scan will pinpoint the exact fault code.
