Check-Engine and Vehicle Diagnostics
SPEEDX AUTO investigates check-engine lights, warning indicators, rough running, starting problems, and other drivability concerns at our Richmond shop near YVR. A fault code identifies a system or condition, not automatically the failed part. We combine scan information with inspection and testing before explaining likely causes and recommended next steps.

Frequently asked questions
Does a code tell you exactly which part to replace?
Usually not. A code points to a system or detected condition and must be interpreted with testing.
Can you diagnose an intermittent problem?
Intermittent faults can require additional time or repeat testing. Details about when the symptom occurs are valuable.
Should I drive with a flashing check-engine light?
A flashing light can indicate a serious active fault. Reduce risk, stop when safe, and arrange professional advice.
