Some days when i get in the car the power steering will be fine but other days the power steering will not be working at all and the red light of a steering wheel will be on the dash board

Does anyone know what this could be as it works most of the time but now and then steering goes really hard cuz the power steering now working

Thanks

Probably a faulty torque position sensor (EPAS column)
