I heard a clunk while driving on highway VLC + Slip came on then didn't come back on after I turned car off. However, check engine light has been on ever since. Car did die on me once at a stoplight and I had difficulty starting a few times.

Mechanic couldn't get the codes with his scanner so I tried the self diagnostic mode. Here's a link to the vid.

I think I got these codes but I am not 100% sure

p1612 - NAT (something to do with the immobilization mechanism) ??

p0335 - crankshaft position sensor, already huge thread on this and i will replace ASAP.

p2001 - NOx Oxides of Nitrogen Trap Efficiency Below Threshold Bank 2
Did a search and couldn't find any info regarding this on Nissan / Infiniti vehicles ??

Anyone have experience with p1612 or p2001?

My baby is at 140k and I want a few more years with her before I find something new to ride <3

 

Ever figure out this code 2001? I have it on my car and it will not start!
