Code P1124 is Throttle control motor relay, but how do i fix it? Slip and VDC light is on, cant rev pass 1500rpm.
replaced both camshaft position sensor and the crankshaft position sensor, did the ecu reset and throttle body relearn and everything seems fine until i start the car again

little back story, i was replacing all my 02 sensors and when i went to start the car it wouldnt, so i tried replacing all the fuses that i can and it turned out to be a ground wire on the front timing cover being ripped off.

 

Did you replace the cam/crank sensors with OEM Genuine Nissan Parts, or Hitachi (the OEM supplier)? If not I strongly recommend putting the factory cam/crank sensors back in because aftermarket sensors are HIGHLY notorious for not working properly.

As for the code, throttle control RELAY, it's located in the IPDM fuse box. Swap it with the AC relay to see if that code goes away (which would make the AC not function if it was actually bad).

Just be sure to identify which relay is which before you start unplugging stuff, take a sharpie and just write on the top of it.
