Recently, however, it seems people are either giving their gas caps an extra twist or the Check Engine Light has had enough because the new CEL king is the engine misfire.
CarMD has an extensive database of Diagnostic Trouble Codes (DTC), which date back to the 1996 introduction of mandated on-board diagnostic technology. Now, CarMD is using that data to shed some light on the oft-misunderstood Check Engine light, and it’s produced its first-ever Annual Vehicle Health Index Report.
Set to be released each April, the Vehicle Health Index Report examines the most common repairs or fixes required as a result of CEL warnings. The gas cap has fallen to number two on that list, while replacement of the O2 sensor has risen to the top spot. Taking home third place is the always-expensive DTC that alerts you to replace your catalytic converter.
