Ford Smax 2.0Tdci 2006: P2263 Error - High Supply Voltage & Charging System Efficiency

Hello to you since some time there is an error in the car:
P2263-supply voltage too high
- charging system efficiency
-current

Ford smax 2.0 diesel 2006

My problem (I did not find similar to my symptoms with this error):

After switching on the ignition, check engie appears, the computer shows an error, I start the car, smokes on a cold engine for a few seconds, calms down, works normally, check engie disappears at the moment of firing, the error can be cleared, but after restarting the same, only on warm no longer buried, but the mistake is still there.
I am worried about the fact that in June I am going a long way and I would not want anything to hurt him.

Please perform diagnostics with dedicated equipment or reliable universal equipment. We will return to the topic of help. The typeface on the screen shows that "delphi" made in china is spreading like the ebola virus.

I do not play mechanic and I was at the diagnostics to delete the abs error and check the engie and took a photo of it so I ask but apparently it will be a sensor for charging

Let's first check the turbine engine (power supply, control)
