Yep, in most cases, but not all. Easy fix and a pain in the arse frankly.

Set the P0121 Error Min MAP to 0 and P0121 Error Max MAP to 100.

Caused me to replace a TPS sensor previously, unnecessarily. I am assuming you are cammed as I have never seen this issue on a stocker before.

Here is a more detailed explanation - all credit to the source.
