Check Engine Lamp

Following a thorough engine bay cleanup (which I would not recommend to anyone), the engine diagnostic lamp has turned on solid orange. Actually it turns off after around 48 hours and then on again after around 8 hours.

Xentry shows Ambient Pressure Sensor fault. Can someone please tell me which sensor is this?

After some research I arrived to the conclusion that this refers to the Manifold Air Pressure (MAP) sensor B U T after changing this sensor with a new one the problem was N O T resolved.

I think this refers to another sensor but cannot figure out which and where this is. Car is not showing other signs of malfunction with normal power being delivered.

Any clue please?
