Does anyone know what this sensor circled is called on my intake? manifold absolute pressure sensor? but I bought a new one and it doesn't fit.

Amazon.com: Wells SU2323 Manifold Absolute Pressure Sensor: Automotive

My 05 Mazda 3 is throwing out cel p2229 barometric pressure high so I thought that sensor was the problem as it was super loose. I wrapped it with zip ties. The idle is starting much higher than it use to at a cold start (about 1.7k vs around 900 rpm before). It does drop as the engine warms up. I'm not sure what's wrong. I have cleaned the throttle body and mass air flow sensor as well. Maybe an air leak as my o2 sensor was stuck rich for a while with cel p2196 and my system was too rich at idle P2188? but those cel have not shown up after driving it for about 150 miles. I also couldn't find an air leak. My map sensor reading was about .99 atm with engine off and around .5 when running? not sure if that info would help. Any ideas?
