P/S light is on but the power steering level is good on 2003 Toyota MR2 Spyder

Power steering level is good and pump is not making noise but P/S light is on and power steering is not working

Asked by for the 2003 Toyota MR2 Spyder
I'm not familiar with this exact vehicle, but I've never seen a warning light for the power steering unless it has electronic power steering. What does the light look like?

I had this problem. We were unable to find the cause but the mechanic reset all the fuses (took them out, set them back in properly) and after driving another few minutes, the power steering came back and P/S light went off.
