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. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

P1250 DTC on a 01 Mazda Protege


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.

P1250


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

Its blowing spark plugs, check engine light is on, runs like it needs a tune up and the exhaust smell is really bad. Diagnostic code is p1250


not sure how cars blow spark plugs, but I would say your problem is a corroded ECU.

not sure what that code is but if te ecu is wet the code is false.

read below

the ecu compartment is under the windshield on the passenger side on E36

you gain acess to it under the hood....
this compartment gets wet, the ecu lays on a flat surface in that
compartment.

the bottom side of the circuit board gets wet and starts corrosion.

remove the ecu, take the bottom plate off, clean the bottom of the circuit
board with alcohol and a soft tooth brush.

you should be able to see the signs of corrosion or conductive build up.

this gunk bridges solder points doing all sort s of wierd things to your
car, including false sensor readings from asc/abs controllers and other
sensors....

all the way to engine failure and worst case burnt and shorted wiring
harness.

I'm on my 3rd ecu, took me and the repair boys a few years to figure this
one out.

BTW: i would get that ecu mounted above that flat surface, use some sort
of standoff to raise it so that it is not laying in the wet.
