Im super noob when it comes to almost everything about cars however i recently went to check out a g37xs 2010 and used a code reader. The code came up as P0106. The car wasnt fully on it was on i believe its called number 2? just for the electrical systems to be working but the engine itself was not on. If anyone can read any of the numbers and what they mean from my video it would be greatly appreciated.

(tried uploading the video directly but its mp4 and also it wasnt accepting the link the other way)

 

Google indicates this is a MAP sensor problem. From what I saw in your video everything seemed alright. Check for vacuum leaks, maybe inspect the sensor for damage.

 

You need an ECU update: https://infinitig37.com/TSB/ITB12-026a.pdf

 

I recently purchased a used 2011 Coupe. Honda dealer that sold me the car replaced the map sensor but service engine soon light just came on after 1000 miles. Code P0106 after analyzed at Autozone. Is any Infiniti dealer required to complete this service bulletin for free?

 

I don't think the dealer will do it for free, unless you know someone or are a very good customer of one.
Usually the charge is no too much, around $50-150 from what I have read here.

They will charge a diagnostic fee to investigate the issue and then maybe a fee to update the ECU.
Shop around and good luck!
