Range Rover 2004 on 2004 Land Rover Range Rover

I just brought my Range Rover to have the water pump fixed and the battery replaced. The check engine light went on after driving it for an hour. My dad hooked up the OBD scanner and the code 1173 came up. What exactly is the error code? What should i get fixed?

Check for vacuum leaks anywhere around the air intake ducting or intake manifold. Look for a hose that is off or cracked. Perhaps a hose got knocked of during the water pump or battery replacement.
