Default Help! DIC is reading wrong

So yesterday my DIC was saying that I had a low tire(18psi) So I stopped put some air in it and then drove back to work(was at lunch) it said it only went back up to 19psi even though on my hand guide it said it was 33psi... Then last night I started my car and checked for nails or holes nothing... checked it with the hand gauge and it said it had 33psi... and the DIC is saying 14 psi... how do I fix?

Resync your TPMS with a speaker magnet.

How do you change the batteries in the TPS? And what do they go for? Money wise?

Then newer C5 sensors ('01-04) cost about $40 each from gmpartshouse.com. A competent tire shop should be able to do the swap - they are just held in place with a nut the goes on the outside of the rim.
