idk where to start. 2 days ago my 2005 g35 coupe rev up took a ****. i was driving to a buddies after work and when i went to leave the car would turn over but not start. i had gas and i knew it wasn't battery related but tried to jump anyway and had no luck. code ran it and got these 4 codes
p1446
p0335
p1078
p1084
did some research and figured it was crank shaft position sensor so i bought a oem one off of z1 and installed the new sensor. (i did this with battery disconnected) after new sensor was in i tried to start car and same issue. it will turn over very slowly and i dont keep it turned over bc i dont wanna fry my starter. i know the other codes (p1078,p1084) refer to exhaust valve timing sensor and dont know if this could be the root of my issue. I also know or think that the p1446 is related to a evap canister vent control valve which i have known about for a while and the cars been drivable w no issues. Very confused and would love some help

 

Currently got same/similar the same issue with my revup.. it’s gotta be an electrical short or something somewhere.

following this thread and will keep posted if I find any solutions..

 

i agree. the p1078 and p1084 are cam sensors which im going to replace tomorrow. not expecting much but i have the sensors so gonna see what happens. will keep you posted.
