Hello, fellow Nissan owners and lovers! I just bought a 2006 Sentra SE R with 74K miles on it -- find of the last 3 decades IMHO! Always wanted one; finally got one! My first car ever was a 1990 Sentra and either myself or my kids have owned 3 more since. This one though is fire! But, it's throwing a P0850 code and I don't know what the actual diagnosis is and I can't find very much info on it. My investigation has turned up a Park/Neutral switch, but this car is a 6spd manual and most forums indicate that this code is for an automatic tranny. I fell in love with this car the first time I saw it and I wanna give it more TLC. The correct diagnosis and fix would be a great start!
