could someone please advise me on the locations of 2 things that have come up as error codes

why cant the internet just give people straight answers,
all im wanting to know is the location of the boost power sensor on my vehicle but when i type in 1.9d 2003 doblo boost power sensor location it keeps showing me images of bloody map sensors on ebay which ive been told on here my vehicle does not have,
anyone would think im asking for the answer to the meaning of life !
the elearn manual isnt much better
