The location of WHAT???

Diagnostic Test Code (DTC) P1250 is a manufacturer - specific code which has a general description of "Pressure Regulator Control (PRC) Solenoid Circuit Malfunction".

The PCM monitors input voltage at Pin number 44 when the ignition is turned on. DTC P1250 sets when less than .44 volts are present. The possible causes are:
> PRC Valve malfunction (open or shorted internally)
> Open or short circuit between the PRC valve and the PCM (control circuit)
> Open or short circuit in the solenoid ignition voltage supply circuit
> Failed PRC valve (stuck open)
> Malfunctioning PCM

Find the fuel rail. On the the end of one of the rails you will see the fuel pressure regulator. It will have a small vacuum hose coming out of the top of it. Follow that hose to the fuel pressure regulator solenoid. Lmk

P1250 Mazda Fuel Pressure Regulator Control Solenoid

Since the code came back immediately this indicates that it is a hard fault. The solenoid is an electrical switch controlled by the ECM. In this case it controls vacuum provided to the fuel pressure regulator. On this vehicle locate the fuel injectors and the rail above them. At the end of the rail is the regulator which on it should have a vacuum hose. Check out the hose make sure there is not leaks or it is not coming apart. If it is okay the other end of it plugs into the solenoid. This is the failed component.
