Good morning, last year I put on a aftermarket throttle body on , ever since then the engine light has been on , it does not effect the drive whatsoever, unfortunately it won’t pass the not , I have purchased a reader and it comes up with p2109 thoroughly attached, any help would be appreciated.

It might need coded to the car believe it or not

Calling @Sid2020  (don't mean to harass you, but your knowledge of this is far beyond my own and you're pretty active here)

Found a wire out of the plug that plugs into the throttle body housing , sorted , many thanks

Glad you got it sorted, open circuit faults  often mean you’ve dropped a feed wire but finding where on the circuit can be a challenge.
