Nissan Repair: Manifold differential pressure sensor, differential pressure sensor, autozone

Question
Mr. Iwashita
I am trying to get my 2001 Altmia to pass emissions, but everytime I fix something there seems to be a new problem.  The problem now is I am pulling the Manifold differential pressure sensor code.  I have looked all over the Internet for the part and even called a couple part stores.  No one has the part. My dad pulled the plug on the MAP sensor and that code came up, so is this part something different or are they one in the same.  Please help.

Answer
Hi Nathan -

What is the code number that is displaying? It is constantly lit, or intermittent? When was the last time you had it diagnosed? Sometimes codes clear itself after a while, or perhaps you can clear it and see if it returns. Autozone will read and clear codes for free.

Can you tell me the history of your fixes? Any info you can give me will be helpful as to how it got to the present condition.

Let me know -
