Engine Diagnostics in Bethlehem, PA
A trouble code names a circuit, not a broken part. Real diagnostics means live data, wiring checks and testing under the conditions that trigger the fault.
This is the step most often skipped elsewhere, and it is the reason drivers from Allentown and Easton bring us cars that already had parts thrown at them.
