Leading indicator – Engine Light on diagnostic
So there’s something not quite right about the way your vehicle is driving, or you’ve got a warning light on your dashboard that was blinking at you yesterday and now it is on steady.
What makes a warning light come on?
Today’s vehicles are manufactured with complex inter-related systems. On-board computers continuously monitor and store information concerning the performance of these systems. A warning light comes on because the computer has sensed a signal from one of the systems or components that has gone outside of its normal operating range. The computer then sends a signal to turn on the light to let you know something is wrong!
Some of the potential causes for a check warning light are not properly tightening your gas cap to engine, transmission or braking system performance issues. While warning lights can go on and the car still appears to be driving “fine”, ignoring some lights can lead to serious issues, such as engine damage or other component failure. In some instances, this can be a safety hazard. That’s why it is recommended to be safe (give yourself peace of mind) and have your car looked at by a certified professional as soon as possible.
