Is the throttle position part of the throttle body or separate from it on a 2006 Nissan Sentra 1.8 L 4 cylinder vehicle?

What is your question?

I don't see a separate throttle position sensor so I am thinking it is part of the throttle body. Please help.

What makes this problem better or worse?

when starting the car or accelerating

How long has your 2006 Nissan Sentra had this problem?
