A Check Engine Code Does NOT Tell You What’s Wrong

In this episode of the Bumper to Bumper Podcast, Dave Riccio and Jon Riggle break down what actually goes into diagnosing a vehicle and why simply pulling a trouble code doesn't tell you what's wrong.They explain how check engine codes work, why some vehicles can have serious problems without storing a code, and how replacing parts based on a scan can quickly turn into an expensive guessing game. They've seen cars come into the shop with thousands of dollars in new parts only for the original problem to still be there.
