I got the engine code P1903 on my 2004 Ford Taurus, what will repair it?

Answer 1

P1903 Pressure control solenoid

The solution for this is to replace the pressure control solenoid. The code definition for P1903 is open circuit of the pressure control solenoid.If this code was reviewed by transmission scan data it would list the pressure control as open circuit. and the O/D light would also be flashing.(if equipt) The location of the pressure control is on the side cover of the transmission Part # F8DZ7G383AB
