Truck has been weak for awhile now. I got these codes last night. Do you think if I just clean the EBP tube and sensor it'll fix this?

 

Probably not. The 2 codes aren't directly related to one another. The P0470 is a circuit code, with possible causes shown in the PCED as damaged EBP sensor, damaged connection and/or damaged PCM. The P1211 is for ICP not controllable.

 

Took the egr tube off today. It was split in the middle. The sensor couldn't have been getting any pressure. I cleaned my sensor and am waiting on a new tube. This should help.

 

Depending on where the back pressure sensor tube was split, it may have overheated and fried the sensor. That could explain the P0470.
