Question type: Maintenance & Repair

Is it possible that a sensor/light was triggered when I didn't turn key all the way
over?  Was told that is what happened last time light came on

The dash lights come on when key is turned and car has not been started, if check light continues to stay on go have the code scanned.


If you turn the key and all the lights come on the dash, and the vehicle isn't started, those are start up lights. This is normal. If any lights stay on while your vehicle is actually put in the on crank position and they do not shut off, then there is an issue. Check your oil if the light stayed on when the car first started and faded, but only if the key was cranked, not the start up lights. Meaning, turn your car on, if the light stays on after the key is cranked to on, there may be an issue. If the light only comes on when the key is in the on position but not cranked, there shouldn't be any issues with warning lights. Check out this website for more explanation.
