No, that tube would not cause that. Possibilities for that code would include a faulty air pump or control circuit, perhaps a faulty vacuum control solenoid, or a leak in the system. Usually how that code is determined, is when the AIR pump is turned on, the system looks for changes in the oxygen sensor reading. If there are no significant changes observed, then the SAIR system is considered inoperative for some reason, and that code sets. That is kind of a nutshell description of the operation. I will attach the code chart for your reference, as well as the schematic. The chart references the use of a scan tool, which you may not have access to. If you know your way around a test light, some jumper wires, a schematic, and an electrical knowledge of a 12 volt DC system, You should be able to isolate a concern. I would start first with checking the fuses, and determining if the air pump can turn on.
Check out the diagrams (Below). Please let us know what happens.
