If someone knows the characteristic of the charging pressure sensor (Denso 079800-4800) at the Peugeot 406 2,2 HDI FAP. I would like to observe the charging pressure in everyday operation in different driving situations. Of course, information about target values would also be important. Reason for the inquiry: Diagnosis message „Environmental protection system engine weak and in the error memory is stored „Lade pressure sporadic too high”. This error message with emergency run comes partly already after short highway ride, in the city traffic everything is in Or dnung. I suspect that at speeds above 2000….2500 rpm is not reliably regulated.
