P2229 code won't go away

I came across a post on Cobaltss.net that says the P0069 won't put the car into limp mode but I don't know it that is true.

The baro sensor is built into the PCM on the TC car. I believe it is also that way on the SC cars. I had to change my PCM for the same code on my 09TC build

For some reason I think the SC has a separate sensor for barometric pressure, but to be honest I don't know where I got that.

It does. My SC car has one on the supercharger, right on top (the MAP sensor). Then it has another one between the Supercharger and the valve cover (on the "back" of the engine, opposite of the serpentine belt side) that is secured to a metal bracket, and it's literally just hanging there in space measuring ambient pressure (the BARO sensor).

It also has a TMAP sensor on the intake manifold under the supercharger snout, but that's a different beast entirely.
