Hi.

The CEL comes on when there are error codes stored in the ECU (main car computer module) memory.

In US you can have a free code scan at the nearest Autozone, or you can have the scan done for half hour service fee at any garage or authorized dealer (to avoid disappointment ask first).

The mechanic will connect a diagnostic tool (OBDII code reader) to the port hidden under the dash.
Report codes here if you need more troubleshooting.

Regards.

Ginko.

Does the engine light come on if the car is overheating?


Hi Jonna.
not sure if this will help you out,but its what i have found on the internet.

Your car's "Check Engine" or "Service Engine Soon" light can flash on for more than 1,400 different reasons, and in the coming months, we're going to share with you what some of those reasons are. The light is part of your vehicle's on-board diagnostics (OBD) system and can indicate anything from a quick fix like a loose gas cap to a major repair like a catalytic converter.
Trouble code: P0217 Engine Over Temperature
If this code is discovered, it means the engine coolant temperature is excessively high under normal engine speed. The engine coolant is overheating if it's around 240 to 250 degrees. This is a critical light! It means your engine is beginning to overheat.
In addition to the check engine light, you might also see some other type of warning on the dashboard, such as a red temperature gauge or maybe the words "engine hot."
The warning lights should come on before any damage to your engine occurs, but you need to shut the engine off as soon as possible.

What does the check engine light mean?



  • A check engine light means a sensor in the car malfunctioned and sent an error to the cars computer and in turn that light came on. So now you have to get the codes pulled and then write them down and the codes themselves will tell you what caused the light and how to go about fixing the car so the light stays away. You can get the codes read for free at your local major parts store. This can be something minor, a glitch or something more major going on but until you pull the codes you will not know.

That drawing you see of an engine is called the check engine light. When that light comes on, it means that it has detected an issue with your car. I flashing check engine light means the engine is misfiring and running it will cause further damage. A solid check engine light can mean anything from a bad fuel pump to a bad transmission. Bring your car to a place like Autozone and they'll scan the onboard computer for free. After the scan, they'll retrieve the code(s) that will narrow down what the issue is...

Emmissions light has come on?


you need to get it scanned, i assume "emissions light" is your check engine light, or the "visit emissions workshop" message, which means, go to a shop and get it checked. The coolant disappearing means you probably have a leak. Another reason to check it,
