Fixed misplaced closing bracket

Not entirely sure if this is right. It stops throwing up error messages when that decoder is used now, but instead everything after a command using this decoder returns something along the lines of the following

>0153: Absolute Evap system Vapor Pressure

>command returned: 
>?
>
>return data could not be decoded
>No Data None

Not sure which is better
