Hi guys I have code p1089 and car goes limp no throttle until code reset. But then same code comes back. Does anyone know what this is?

 

From the FSM:
P1089, P1092 VVEL CONTROL SHAFT POSITION SENSOR Description
VVEL control shaft position sensor (1) is placed on VVEL actuator sub assembly and detects the control shaft position angle. A magnet is pressed into the arm on the edge of control shaft. The magnetic field changes as the magnet rotates together with the arm resulting in the output voltage change of the sensor. VVEL control module detects the actual position angle through the voltage change and sends the signal to ECM
