I recently had my 04 Quest SE tuned up (plugs & Coils ) not dealer. It ran well then a engine code light appeared P0507. I was recently told I need a new Throttle body and that it must be done by a dealer in order to reprogram the throttle body system. dose anyone have any experience with this system, and it it true it can only be repaired by a dealer.
Here’s the OBDII sheet for P0507: http://nissanhelp.com/diy/obd_codes/p0507_nissan.html
There is a TSB for P0507: http://x.nissanhelp.com/forums/Knowledgebase.html?s=&catid=231&filter=&sort=d&page=1&pp=10&keyid=180
I would read over both of those documents. They should give you an idea if you need to go to the dealer or not.
