FAQ

Engine Diagnostics FAQs

Straight answers from our Newark technicians

It can be anything from a loose gas cap to a misfire or a failing sensor. The light only tells you a system reported a fault — our scan and testing identify the exact cause, and we explain it before recommending any repair.

If the light is steady, get it checked soon but you can usually drive. If it is flashing, stop driving — a flashing light usually means an active misfire that can quickly destroy your catalytic converter.

Estimates are always free. If a deeper diagnostic procedure is needed to isolate a tricky fault, we tell you up front and quote it before we start — no surprises.
