Frequently Asked Questions about Check Engine Light Diagnosis in San Diego

How much does a check engine light diagnostic cost in San Diego?
Many shops in San Diego 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 San Diego?
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.
