Where is the MAPS/Barometric Solenoid Valve located on a 2001 Infiniti Q45t

Question

My check engine light was on. It was due to bad knock sensors. They were both replaced. And all my vacuum hoses were replaced at that time as well. After the repairs, the check engine light stayed on. I was told it was the MAP sensor. It was replaced. But, the check engine light did not go away. I was told it was the solenoid. And that was replace to. But the code, P1105, and light is still there. What could be keeping the light on with the code?
