The 1401 code is for a DPFE switch or connector that is not sending the correct signal the PCM expects. The 1288 code is for a temperature sensor which may be showing a higher cylinder head temperature due to low coolant levels, blockage of water flow or bad thermostat.

The DPFE gives readings of the mix of exhaust gas returning into the intake manifold to be burned again to lower emissions.

The combination of these 2 codes can mean that too much exhaust gas is too frequently going into the intake manifold and is overheating the cylinder head causing the 1288 code. So fixing the DPFE may eliminate this secondary error which may reset itself after the first problem is fixed.

SOURCE: How to Change a Fuel Pump in a 2001 Ford Crown

STEPS TO CHANGE FUEL PUMP

  1. Park the vehicle in a safe place and make sure there is enough room around the back of the vehicle for you to work and move tools around.
  2. Start the engine and let it idle while you relieve the fuel system pressure by removing the fuel pump fuse or relay from the fuse box. Wait a few seconds for the engine to stall, turn the ignition key off and replace the relay or fuse.
  3. Raise the back of your car using a floor jack and support it safely on jack stands.
  4. Disconnect the fuel tank filler pipe and the fuel pump connector located above the cross member underneath the vehicle.
  5. Disconnect the vapor tube from the tee connector on the right side of the car-passenger side-and the vapor line from the canister tube.
  6. Support the fuel tank with a jack and remove the nuts from the holding strap using a wrench or ratchet and socket. Move the strap away and lower the fuel tank. Discard the fuel tank mounting studs.
  7. Unplug the pressure transducer electrical connector located on the top rear corner of the fuel tank.
  8. Clean the area around the fuel pump mounting flange and remove the flange mounting bolts in a crisscross pattern.
  9. Lift the fuel pump assembly off the tank. Replace the new fuel pump in the assembly and install the assembly in the tank. Install the flange screws and torque to 89 inch lbs. (10Nm) using a crisscross pattern.
  10. Raise the fuel tank to its mounting position, install the strap using new mounting studs and torque the nuts to 26 foot lbs. (35 Nm).
  11. Connect the fuel pressure transducer electrical connector, vapor tube to the tee connector, vapor line to the canister tube, fuel tank filler pipe and fuel pump electrical connector.
  12. Lower the vehicle, start the engine and check for leaks.

Water pump failed. Car overheated. Engine lost power. Car smoke out from back of engine and from rear of car. I replaced water pump. Car still smokes when I drive it. Still has no power.


Notorious for intake leaks, the composite plastic intakes crack and leak coolant-as to the lack of power, you mght have overheated it and done some damage to the engine. There was a recall (information below) for the 4.6 for the intake-the overheating and lack of power means you should at least have compression checked and go from there-you may have bad head gaskets or worse. Do a compression test before you do anything else.

Ford Motor Company will extend the recall (01M02) on 4.6L V8 equipped vehicles with plastic intake manifolds. Some of the composite intake manifolds used on 4.6L SOHC engines may develop fatigue cracks at the coolant crossover duct. This condition could result in engine coolant leakage which, if not serviced, may cause engine overheating. Complete loss of coolant may result in engine damage or engine failure.
The updated recall now includes:
• Certain 1996 through 2001 Model Year Crown Victoria Police Interceptor
• Certain 1998 through 2001 Model Year Crown Victoria with Taxi
• Certain 1998 through 2001 Lincoln Town Car Limousine and Livery Prep Package
• Certain 1996-2001 Crown Victoria Taxis, Police cars and Lincoln Town Car Limousine and Livery cars.
• Certain 1996 through 1997 Crown Victoria Police Interceptor Vehicles with 4.6L SOHC engines built at the St. Thomas Assembly Plant from the beginning of production for the 1996 Model Year through January 28, 1997.
• Certain 1998 through 2001 Crown Victoria Police Interceptor Vehicles with 4.6L SOHC engines built at the St. Thomas Assembly Plant from November 22, 1997 through December 15, 2000.
• Certain 1998 through 2001 Crown Victoria Taxi Vehicles with 4.6L SOHC engines built at the St. Thomas Assembly Plant from November 22, 1997 through December 15, 2000.
• Certain 1998 through 2001 Lincoln Town Car Limousine Prep Package and Livery Vehicles with 4.6L SOHC engines built at the Wixom Assembly Plant from November 22, 1997 through December 15, 2000.
