The importance of the check engine light and what most people miiss

Whatever you do, don’t ignore your check engine light if it illuminates suddenly while you are driving. The check engine light is a frustrating diagnostic tool, as it can indicate any number of issues with your car, from a cranky spark plug to pending engine failure. Don’t second guess the problem! Get your car in to your repair shop as soon as possible to avoid possible permanent engine damage.Whatever you do, do not take your car to an auto parts store for a check engine light diagnostic. The employees are qualified only to interpret stored trouble codes, not diagnose the problem. Consult a qualified engine repair technician when your check engine light goes on. Your technician will perform a scan test for stored trouble codes, check sensors and components to eliminate possible sources of the problem and determine an appropriate cause of action to correct it. Auto parts store employees cannot do that.
