Transversal acceleration sensor

Good afternoon everyone.
I am new in the forum and I am a little lost.
I have been hearing the page in case there was any post that could tell me something, but I still still at the beginning, so I have decided to write.
I have a lagoon II 1.6 that has a failure in the transverse acceleration sensor as they have communicated in the workshop, someone can tell me where this sensor is located and if possible their repair outside workshop, there are no times for expenses. Thank you.
