Hello Guys.

I hope you can help me out.

My Z'ed keep's giving me a hard time.. Im getting error code P2122, P2138 all the time and the car goes into LIMB mode

I had my OBD reader on it several times to clear the code without any luck..

P2122 Accelerator Pedal position Sensor
P2138 Accelerator Pedal position Sensor

I have changed the accelerator pedal sensor, and i've also changed the plug going to it since the previous owner had given it a hard time.

I also tried tweaking the connectors on the throttle body a little to give it better connection without any luck?

Anybody has an ide on what this could be? Should i replace the throttle body or is it something else? Sometimes i can get it startet without having the error code but i can start in 30sek og 30min later.. In that time the car works Perfect!

I cannot be the only guy experiencing this

 

Daily bump? Anybody?

 

 

HI Brian, and welcome... A couple of questions:

1) What year/model is your 350z?
2) Did you replace both the Accelerator Position Sensor and the Throttle Position Sensor?
