    I have the same code on my Range Rover Sport 2015 having google looking for an answer I came across the link above.

    The MIL is illuminated on the IPC with Diagnostic Trouble Code(s) (DTC) P0234-77 stored in the Powertrain Control Module (PCM) which may be accompanied with DTCs P2463-00 and P246B-00. CAUSE: Component failure. ACTION: 
    Follow the instructions below. C O N D I T I O N S U M M A R Y : 
    PART NUMBER DESCRIPTION QUANTITY 

    LR078546 Intake air shutoff throttle
    LR063121 Inlet hose clamp
