The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to a parts store or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.

What does orange light on rev counter mean?

The orange light is used for a 'shift' signal. It means 'shift into the next gear now'. If your tachometer/rev counter has an adjustable setting for this light, you can set it to come on when you're at peak horsepower or torque and want to shift into the next gear. This comes in handy for getting the best performance out of your vehicle's engine while drag racing. It can also be set up to remind you to shift at a lower rev than normal to help you save fuel.
