Hi guys, I have a 1993 SL 500(129.067) with the M119 engine(M119.972) and Bosch LH -Jetronic with a fault code 13 for an open/short circuit intake air temperature sensor. I am thinking it must be built in to the air mass meter on this model as there are no sensors in the air filter box or intake pipes, would this be correct? Thanks for any replies.
