Please help , Have a 2007 RRS HSE have P2098 code Mechanic says O2 sensors look good , that error may be a Vacuum leak
found loose hose no idea where it goes.
Please someone look in the engine and locate the hose and connection

Picture is in the Gallery for location of loose hose

Isn't that the battery vent pipe? It vents the hydrogen produced during charging away from the battery/fuse box etc. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

Ok what do you recommend I do for the P2098 code

Check around the throttle body/rear of plenum chamber for any loose pipes, not sure about the 4.4, but on the 4.2 there is an air pressure sensor that can blow off with age.
