her is link with file attached to large to post here thanks

 

P0140 is a fault in the rear O2 sensor, driver side. Won't prevent the engine from starting/running.
Unless the sensor is still used, it's probably not been deleted, and the code is set.

 

Sorry put in wrong letter its a U code sorry and it comes up body controll module issue i made correction on post do you have any other ideas

thanks
