Question type: Maintenance & Repair

Hello,
When I turn the key in my car the service engine soon light is one and
remains on, but as soon as I start the car it disappears. When I say remain,
every lights are on but just for a couple seconds, service engine on actually
stays on (until I start the car)
Thank you for your time!!

That's the way it works, the other lights turn on then go off as a circuit check but the check engine light stays on until it starts because if there's a problem with the engine control it will remain on until repaired. I hope this helps. Take care.

Thank you for your answer. I'm not sure I understand does that mean there's an issue and o should have it checked? Last time it was on it would stay on all the time.
