Good afternoon i can help you the fault #p047b is for a faulty exhaust pressure sensor located next to the coolant reservoir and the other fault you should have to worry about it fault # ***** its related to low fuel pressure more then likely you have fuel contamination in the high pressure fuel pump , Have the solenoid off the high pressure fuel pump remove and check for metal contamination this will cause the vehicle not too run anymore if the high pressure fuel pump is failing and breaking apart . I hope this helps .Please dont forget to provide feedback/rating we as experts rely on this thank you
