to clear a "check engine" light on a Volvo 940:
First you have to plug the test cable into socket 2 for fuel injection or 6 for ignition codes. The codes are read as groups of red led flashes.
1)turn the ignition switch to "run" position, press the diagnostic button for 5-8 seconds, then release. the LED would come on.
2)press the diagnostic button for over 5 seconds until the LED goes off.
3)press the diagnostic button for 1-3 seconds, if the LED shows "1 1 1" , that means the DTC have been cleared.

Did you try unhooking the battery
Trying to clear the check engine light in a Kia Sorento yourself is not recommended. The check engine light could indicate a serious problem and the car should be inspected by someone qualified.
It is the one next to the service light.....second to the right.

I clear the check engine light with a Scangauge II. But most ODB-II devices can read and clear the code.
disconnect the battery for 1min or so the light will go off
A check engine light displaying on a Volvo V40 means maintenance is needed on the car. Check the car's instruction manuals to see each mileage checkup recommended by the manufacturer.Ê

You do battery reset, if that doesn't help then go to diagnostics and Engine ECU and check what code does it give.
A scan tool is required to clear the check engine light. If the failure is not repaired, the light will return.
