There may be a wire from the sensor that is loose or grounding incorrectly. Open your doors and u should see a Little button on the inside frame. Check all these for all the doors to find the culprit
Check the brakers that are activated by the doors, if one of them is broken then the lghts will stay on forever. Don´t forget trunk compartment light if there is one or the light in the engine bay.
Does it stay on forever? Or does it eventually go out? FriPilot

car door light stay on
On my 2002 sportage 2-door, the door ajar light stays on when the tailgate is not locked. with the key.

To identify which door is causing the "door ajar" light to stay on, first, visually inspect each door to ensure they are fully closed. Next, open and close each door one at a time while observing the dashboard light. If the light turns off after closing a specific door, that door is likely the culprit. Additionally, check the door switches for any signs of damage or malfunction, as faulty switches can also trigger the warning light.
The door lights are supposed to go out when the circuit is completed by closing the door. A loose or corroded ground wire in the door latch can cause the lights to stay on.
From what I found, it means "Stay with me Forever" in Quileute.
Many rangers have a micro-switch built into the door latch that grounds when the door is shut. If the switches become dirty, they will cause the dome light, chime, and door ajar light to stay on. A few shots of contact cleaner should do them justice.
