Nissan350-78

Hello guys new to the forum
i have this 2 codes that have been turned into a nightmare
My vehicle is a 07 350z manual transmission
I have replaced the throttle bodys twice and the pedal accelerator twice as well i have performed the learning procedure accordingly and every single time is like i haven't replaced or programmed anything
i have checked the 5 volts to each of the throttle bodys checked grounds and nothing seems to work
Been dealing with this issue for a couple of years on and off
any help will be appreciated

Are you using OEM or aftermarket throttle-bodies? The P2135 code is thrown when the wrong voltage for the throttle position sensor is sent to the PCM/ECU (not voltage received at the throttle-body itself). I suspect you have a wiring fault if you have already replaced all the "suspect" parts. I suggest biting the bullet and taking it to a shop to have the fault properly troubleshooted before throwing more parts at it.
