OBD-II Trouble Code Technical Description
Fuel System Over Pressure Relief Valve Activated
What does that mean?

This generic powertrain diagnostic trouble code (DTC) typically applies to many OBD-II vehicles. That may include but is not limited to vehicles from Land Rover, Ford, Alfa Romeo, Toyota, etc.

When your OBD-II equipped vehicle exhibits a stored code P000F, it means that the powertrain control module (PCM) has detected excessive fuel pressure and the over pressure relief valve has been activated.

If there are fuel volume regulator codes or fuel pressure regulator codes present, you should diagnose and repair those before attempting to diagnose the P000F. Fuel system over pressure relief valve activation is most likely a reaction to a malfunction in the fuel pressure regulation system.
