Frequently Asked Questions
OBD (On-Board Diagnostics) collects data from sensors monitoring engine performance and emissions while serving as a diagnostic alert system. When a problem occurs, the system stores trouble codes that we retrieve and analyze to diagnose the issue.
A basic diagnostic test typically wraps up in 1 to 1.5 hours. Complex issues or intermittent problems potentially extend to 2 to 3 hours for proper diagnosis.
Specialized equipment scans engine, transmission, throttle, and electrical systems to identify problems ranging from minor sensor issues to complex electronic malfunctions. We review trouble codes, live data, and perform targeted tests to find the root cause.
A solid check engine light usually indicates a non-emergency issue, but you should have it checked soon to prevent further damage. A flashing check engine light means a serious problem, typically engine misfire. Pull over safely and call us immediately.
Free code reads only tell you the code number, not what is actually wrong. Codes are a starting point for diagnosis, not a final answer. Replacing parts based only on codes often leads to wasted money on unnecessary repairs.
