Automotive FAQ

Quick answers about warning lights, codes, maintenance and repair decisions.

Can this site diagnose my car?

No. It helps organize observations and questions. Diagnosis requires vehicle-specific testing.

Is a code scan a diagnosis?

No. A trouble code identifies a detected condition or circuit, not necessarily the failed component.

When should I stop driving?

Stop for braking or steering changes, smoke, fuel, overheating, low oil pressure, an unsafe tire or major loss of control or power.

Why are there no repair-price tables?

Prices vary by vehicle, diagnosis, region, labour, parts and scope. This site explains estimate structure; Vehiclenomics handles deeper ownership economics.

Are tool entries saved?

No. They remain in the current browser page.
