2013NV2500 Posted December 11, 2020 This van is giving me one fit after another. If anyone here can share techincal stuff concerning these 2 codes such as scan data, stft, ltft, airflow and O2 sensors, etc please respond here and I will share the data I currently am seeing. I am not on top of Nissan diagnostics at all. Have been a tech for many years, however in my area we simply never seen many Nissans. I now have moved to a larger area and have bought one that is eating my lunch. I have a Verus Edge, can screenshot specifics, discuss in tech lingo, just need to figure this thing out.

aztec Posted December 12, 2020 I'm not all that tech savvy but if I had multiple, unrelated codes I'd be looking at the wiring harness for rodent chew and checking multi pin connectors for corrosion. After that the service manual has a flow chart for trouble shooting all the sensors. There is a link on here somewhere for downloading the manual.

radin2son Posted December 12, 2020 nissanhelp.com (may not be Nissan) lists all the codes/cause. It sends your to another link, however. 525 codes if I read it correctly. Quote Share this post Link to post Share on other sites
