code 1020 eccentric shaft sensor power supply

[byebyev8]

After letting my car m6 sit for a month I installed the bms intake and charge pipes and got this code 1020 which seems to be the eccentric shaft power supply sensor. Does anyone know we’re this sensor is? I returned to the stock intake cleared the code and it came back. I do have a aftermarket warranty on the car but If it’s something as simple as a plug that Came loose i rather save the trip to the dealership.
