boost preasure sensor & atmospheric preasures
 

Hi All,

I have 2000 Volvo s80 with 96k Miles.Yesterday its displayed the check engine warning.Today i went to the dealer and they said first they have to Diagnose the problem.They charged me $150 for Diagnosing and said my car need to replace two parts which are 1)Boost Preasure Sensor and 2)Atmospheric Preasures which are coasted $700 almost.

Can some please help me is it possible to replace these two parts my self or the dealer can only change these and it would be great if you guys suggest me how to i clear the truble codes for disappearing the check engine sign.

Can some one help me please in this regard.
