What’s New
It seemed like a good idea at the time. I accidentally planned a business meeting in Montreal at 9:00 AM on a Tuesday morning, followed by two days at Lime Rock on Wednesday and Thursday. Of course, with roughly four hundred miles each way between home in New Jersey and my client’s office in Montreal, it would be pretty tough to make the round trip in time to turn around and head back out for the two and a half hour ride to Lime Rock. So, I decided to do what any reasonable person would do; I packed up my twenty seven year old 911SC, threw in my clothes bag, briefcase, tools and helmet, and headed up the New York Thruway into the Great White North.
It all was working out beautifully. The three liter engine of my 911 settled into a beautiful, cacophonous mix - part mechanical, part whirring from the huge engine fan. I got into such a groove that I drove non-stop, past Albany, past Saratoga, through Lake George, all the way until the “sortie” signs clued me in that the US/Canadian border was approaching. I took the last exit in New York for a McDonald’s and gasoline break.
These are just a few of the many things that we have heard over the years regarding that infamous and dreaded little light in your dash: the Check Engine Light (CEL) But what does that little light actually mean? And unlike the Mayan prediction of the end of the world, your problem may be very minor – or it just may indicate a larger, more obscure problem.
On-Board Diagnostics System
Use of the CEL began with the introduction of the On-Board Diagnostics II system (OBD) starting in 1996. This system is a government mandated vehicle component that automatically checks and tests various vehicle emissions control items.
