The problem you now face is what to do about the check engine light. There are literally thousands of diagnostic trouble codes (DTCs) that the check engine light might refer to. The only way to even get started is to connect a scan tool. Some auto repair shops charge for auto diagnostic services, but some places, such as autoparts stores, offer to scan your vehicle for free. You are probably wondering, “Why should I pay for auto diagnostic service when someone will do it for free?”
Do You Really Want To “Chance” So Called “Free” Auto Diagnostic Services?
The truth is, at best, you’ll get a printout of the DTC and a “guess” as to what the problem might be. It’s an autoparts store, after all, and their business is selling parts, not necessarily fixing cars. At worst, you might buy parts that don’t end up fixing the problem. In the end, you got a “free” auto diagnostic check, but you wasted time and money on unnecessary parts. Where’s the value in that?
