Engine Malfunction Light Flashing While Ramping

First of all, greet everyone. I have a 2012 model 206 plus 1.4 HDI vehicle, the engine light flashes momentarily while ramping. Has anyone happened to you before? I wonder what is the solution? Thanks in advance.

Have you checked the water of your car.

the water may be missing or the sensor on the reserve water tank is faulty.
