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
