Punto Evo Neutral Position Switch

[Jamie_hill_035]

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.

Jamie.
