Frequently Asked Questions
Is a check engine light urgent?
A steady check engine light means there's an issue that needs attention but isn't immediately dangerous. A flashing check engine light indicates a serious problem (usually engine misfire) — reduce speed and get it diagnosed immediately to prevent catalytic converter damage.
What's the difference between a code read and a diagnostic?
A code read ($0-$50) tells you WHAT code is stored (e.g., P0420). A proper diagnostic ($50-$200) tells you WHY — the technician tests specific components to identify the root cause. A code is a starting point, not a diagnosis.
Why does car diagnostic test cost different in McKinney than other cities?
McKinney's costs reflect local labor rates driven by the diversified economy, varied climate conditions that affect materials and scheduling, and moderate permitting requirements. The balanced labor market also influences competitive pricing.
