First step I checked the wire for the pressure sensor was good no short appear,erase fault test drive after 120km fault appear again for test run outside wire for the effected pressure sensor pin same fault appear again, after that replace the pressure sensor problem not solved replace pdk control unit same fault still appear every time fault reappear after driving more than 100km. vehicle battery and alternator are in good condition. Piwis tester is the latest version I don't know what I'm missing all the possible causes are done fault still appear.
