Error with car U1715

[Gittins]

Got a problem with a punto evo 2010 1.4 turbo 16v mopultiair

On the dash messages come up with ESP unavailible and hill hold unavailible

I scanned for codes on the engine and got back Error U1715 - Side Acceler./Yaw node (NYL)

Does anyone understand this error? I cleared it but it returns

Best asked in the Punto Evo (etc.) section.
