Normally OBD doesnt read exhaust pressure on these vehicles but you dont give a year so its difficult. you have 3 codes
P1412 Land Rover Secondary air system fault bank 1Drive cycle D:Signal implausible
P1415 Land Rover Secondary air system fault bank 2Drive cycle D:Signal implausible
and
P0134 Generic O2 Circuit No Activity Detected (Bank 1, Sensor 1)
all would probably point to a secondary air problem
hope thats some help, you need to give more details
cheers

Wish I could help you with the SAI, but I have been fortunate to not have one or have any experience with them.
