Hi there. Was wondering if someone may be able to help me. I’m working on a 2011 Punto Evo with stop start. The initial issue was a fault airbag control module. It was replaced with a second hand one that had the crash data erased on it. After fitting this airbag module the Engine management light has illuminated and is showing code P1850-15: Neutral position switch short circuit... I have searched in different locations and spoken to to dealership for the location of the sensor. I cannot find this sensor located on the vehicle at all. Is it possible that it was never fitted and something in the engine ECU has to be configured? many thanks.
