Frequently Asked Questions — Diagnostic in St Louis Mo
What triggers a check engine light?
The check engine light can indicate issues ranging from a loose gas cap to a failing catalytic converter, oxygen sensor, or more serious engine or transmission problems. A diagnostic scan identifies the exact code.
How much does a car diagnostic cost?
A standard OBD-II diagnostic scan typically costs $50–$100. Many shops apply this fee toward the repair cost if you proceed with the service.
Can I drive with the check engine light on?
A steady check engine light usually means it's safe to drive in the short term, but you should get it diagnosed soon. A flashing check engine light indicates a more serious issue — stop driving and get it checked immediately.
