Oil level marker - Platina/Renault C II

Hello,
before making the maintenance of the 80mil kms (time strap change, alternator strap, oil, filter, etc ...) I worked for the electronic marker of the oil level when I gave the button after teaching it, now it does not work, someone knows if it was that a detached sensor stayed, or is a fuse burned, etc ????

Greetings,
Robinson

It should be disconnected looking for it usually goes in Moor's block either on the side or by the front, but I think yours is on the side by the motor tracera.
