What DTC do you have? Have you tried looking in the FSM for the DTC description and followed the trouble shooting procedures?

I had the same issue, its your throttle position sensor, it will cost about 160$-180$. Remember you cant buy the sensor alone because it comes its the pedal and and everything already . Its a easy fix Good LUCK

Default Solution

I had the p2122 and p2127 on my 350z drivetrain and I replaced the APP sensor. At first it did not work and I saw a lot of people saying you had to replaced the entire pedal assembly which seemed dumb to me. So I looked at the switch and found out if you install it with the piece that slides in the top of the pedal resting closed it won't work. You have to install it in such a way that it is preloaded and the sensor is just slightly open. Otherwise it doesn't allow the .9v through it and won't work. Also there is also a lot of crappy sensors for sale aftermarket wise so make sure you buy an OEM one, it is worth the extra $10 bucks.
