2006 SE, I know these issues have probably all been addressed ad naseum, but I can't seem to find a answer that fits my exact issue. First off I am getting the P0335 crank shaft position code. Which I assume is the REF (not POS) I look at all these auto parts store websites and even call a Nissan dealer and they all say that this vehicle only has one crank shaft position sensor. I guess they are calling the POS the crank shaft angle sensor. So I am going to have the ckp sensor replaced. Also getting the P1800 VIAS/V circuit malfunction code. Should I be worried about this and where can I find this part to replace? Also getting the P0744 code for torque converter clutch circuit. The guy I bought the car from swears he just replaced the torque converter and valve body and says that the faulty crankshaft sensor could be causing this code? Finally I am getting a P0448 code for EVAP issue. Again, should I be worried about this? Any help anyone can give would be appreciated so much. I am obviously a newbie. Had the car for 4 days and it went into limp mode has 94,000. Damn, already I'm in love with her, but so scared after reading so many of these posts. HELP!

Now this morning won't shift, had to put in manual mode to get it to shift...

First welcome to the forum, second you should familiarize yourself with this website. There is a search bar at the top which doesn't do exactly what it used to when I first started here so narrowing things down on the site can be tough. You can do an advanced search which will help you find for our generation car's posts. http://forums.maxima.org/search.php Use this link to help in your searches. It gives you the option to select just the 6thgen maxima on the right side by highlighting 6thgen and unchecking the "Child forums" box.

Now on to helping narrow down your problems. I think you are on the right path with the Crank sensor. http://engine-codes.com/p0335_2004_nissan_maxima.html There is a picture showing you where it is located. For the P1800, I don't have experience with this and dumping money into it. I recommend looking into a VIAS Block off plate http://www.nwpengineering.com/Phenolic_Spacers.html look about 3/4 of the way down the page for the BOP. As for the P0744 http://engine-codes.com/p0744_nissan.html There is a recent thread covering this same issue. Not sure if it has been resolved yet.
