Check engine light diagnostics

A code tells you which system noticed a problem, not which part failed. We read every module, look at the conditions when the light came on, check for factory bulletins on your VIN and test the circuit, so the first repair is the right one.

Solid vs. flashing

A steady light means a fault has been stored. A flashing light usually means an active misfire bad enough to overheat the catalytic converter. If it is flashing, reduce speed and get it in as soon as you can.

Why a free code read is not a diagnosis

A parts store scan returns a code number. The same P0171 lean code can be a vacuum leak, a weak fuel pump or a dirty mass airflow sensor. Testing is what separates a $20 fix from a $600 guess.
