What is the code B2604 on my 2011 nissan altima

Question

I was having problens with my mass air flow sensor and when I took it to the shop they said another code came up and it was b2604 but did not tell me what it is and I'm really not having troubles with anything else. Help?

Answer 1

B2604 is related to the PNP sensor which is built into the shifter (P, R N D...)

if you are under power train warranty you can take it to the dealer, 

also the CVT transmissions have an extended warranty, just in case the (Transmission control module) TCM is bad.
