p1197 Code on bmw 325i 2006

[arikpls]

Hello, I recently got the code p1197 and i find some sites say its the o2 sensor. Does anybody have any idea how to fix that or how much it would cost to repair?

From my research I found that code is linked to the Differential pressure sensor intake manifold. I'm not a fluent BMW tech, but I don't see how an oxygen sensor would fix this. I assume this measures the pressure in the intake manifold. I predict either the sensor is bad or the harness is damaged.
