Is it safe to drive with this code?

Not recommended. Driving with a high-pressure fuel system issue can lead to engine performance problems or damage.

Will this code come back after clearing?

It can return if the underlying issue, like a faulty sensor or pump, isn't fixed.

Why does this code sometimes pair with a low fuel pressure code?

If the high-pressure fuel pump is failing, it can cause both high pressure sensor errors and low pressure conditions in the fuel system.
