Alternator is no longer working properly.
The ABS system requires 10.5 volts to operate, so if the charging output of the alternator was below this level, the ABS light would come on, and the ABS system would shut down. If the output is far below this level (say, zero, if the alternator failed), your battery would not charge, and the car wouldn't start. Have your charging system checked.
Defective alternator.
It would be light black.
Yes, a defective fuel cap will make the check engine light come on. It will alert the car that its not getting good gas mileage.
Take your car to an auto parts store such as AAA Autoparts or Pepboys. They will check it for free. There are many reasons why the light could come on.
To travel at the speed of light you would have to BE light so i guess you would became an even brighter light The switch to turn on the lights will work but no light will come on as you are already at that speed
We have no temperature gauge in our car. Didn't come equipped with one. It probably has a warning light that would illuminate if the engine was getting to hot.
Im guessing there is something wrong with your car!
