When one of these lights comes on, it means that one of the sensors or computerized components that monitor your vehicle’s engine system is indicating something. Though nothing may seem wrong with the car, we suggest that you bring the car in for aninspection.
The tune-up was historically associated with the routine replacement of key ignition system parts like spark plugs and ignition points, along with some basic adjustments to help “tune” the engine. Mounting pressure for increased fuel economy and lower emissions drove the car manufacturers to adopt electronics and to do away with ignition points in the ’70s, along with the carburetor in the middle ’80s. This eliminated the need for the replacement and adjustment of a growing number.
As the pace of technology quickened, the procedures required to perform a traditional tune-up changed dramatically. Highly sophisticated ignition and fuel systems are now the norm, using one or more onboard computers to control critical engine and transmission management functions. Things that were once handled mechanically are now controlled electronically through the widespread use.
Because vehicles have changed so much over the years, the Car Care Council has introduced the 21st Century Tune-up. This program is designed to help re-define and educate motorists as to what a tune-up should consist of on today’s modern vehicles.
“There is a misconception that today’s modern vehicles don’t need tune-ups because they never break down, but that simply is not true,” said Rich White, executive director of the Car Care Council. “If you’re at work and your computer goes down, you can’t get any more work done. It’s the same with your vehicle. If the vehicle isn’t being properly maintained, you’re not going to get where you want to go.”
