Fuel Pressure Hi C70 2007

My daughter's C70 has been throwing a CEL with the code P0193, Fuel Rail Pressure Sensor Hi. I've cleared it once and it's come back. She says the car is "stuttering" which I need to drive and confirm.

My OBDII scanner's Freeze Frame function shows the incident at 312 seconds, 1,700 rpm, 25% throttle and a fuel pressure of 225 inHg. Is that excessive?

I can replace the sensor and see if that's the culprit or is it a fuel pump issue? I don't have a gauge to check rail pressure but could find one at AZ.

Thanks,

Erwin
