2007 Ridgeline with 98k....engine light came on, vtm-4 light as well....I have worked on motorcycles for decades, did my research, thought about it....realized the spark plugs have never been replaced!..they are NGK iridium type.....I read that if the module picks up an intermittent miss on one or more cylinders, it will confuse the very sensitive pick-ups that warn of traction loss, which illuminates the vtm-4 light, as well as the engine warning light....I found the number 5 plug ( the one center and front on the engine), and igniter to be dirty and the plug tip had separated internally from the ceramic insulator..making the spark have to jump, causing misfire at low rpms, and thus causing all these warning lights...with 6 new plugs, all lights are off...praying helped too......JUST GOOD INFO TO SHARE!
