A check engine light can be triggered by anything from a loose gas cap to serious internal engine faults. Driving without knowing the cause can risk further damage or lead to costly repairs. Pit Stop Pros uses professional-grade OBD-II scanners to read both generic and manufacturer-specific trouble codes, then perform targeted inspections to find the root cause — not just the symptom. We break down the problem in plain language, outline repair options, and can clear the code after repairs to verify the fix. Our approach ensures you only pay for necessary repairs, avoiding costly trial-and-error part replacements.
