Help with flex pipe and TPMS

Hi guys,
I have a leak in my flex pipe so I want to buy the part from ebay since rockauto does not list it anymore, the thing is that I have differente sizes 2". 2-1/4", 2-3/8, do you know what is the correct option for an HHR 2008 2.4lt?

also 1 of my TPS sensors was failing so I bought a new one from rockauto, but the learn process is not working by inflate or deinflate the tire, Is there another way to delete the Code nad have the TPMS working?
O I almost forgot, also the Cruise control is not working I think since the TPMS problem Do you know if it deactivate the CC?


Regards and thanks for any help.

The cruise control is because of a MIL code , when my flex pipe cracked it set a code , so no cruise control, it can also be turned off due to a burnt out brake light .
I choose to replace the whole pipe $168.00 , 3 studs and 2 nuts remove and replace the O2 sensors and done , that was in April 2014 no problems since.

Could you do the TPMS position thing before? Like when rotating the tires. If no, there is a tool, EL-50448 or OEC-T5, made for the job. About $80.

sure, I did it 2 or 3 times before, by swithin on and then lock and unlock key, double bip syaing that is ready to learn, then front driver iluminated, inflate or deinflate and then a bip and so on, but now Im now having the bip when inflating the tire. :S.

for the CC I will check the stop lights.

What about the flex pipe dimension? is it 2 1/4 the correct part?

Just the new one? Then you must have got the wrong TPS.

2 1/4 for the 2.4 but that's by the Internet, may I suggest you measure your down pipe!

The flex pipe issue should resolve the code, as it can be from an exhaust leak , which would be the cracked flex pipe
