Ford 04 v6 po 0193 fuel rail pressure high input

Fuel pressure outside nominal range. Check pressure at fuel rail.

Does the Vehicle start an run ? What engine does it have ? 4.0 or 4.6 L You vehicle has electronic returnless fuel system , Fuel rail pressure sensor , FPDM - fuel pump driver module . The fuel pump driver module controls the fuel by pulse width modulation
Pulsewidthmodulation (PWM) is a powerful technique for controlling analog circuits with a processor's digital outputs. PWM is employed in a wide variety of applications, ranging from measurement and communications to power control and conversion. The PCM - engine computer uses the fuel rail pressure sensor input to send commands to the FPDM .
What code ? P0--- what ?



P0190 - Fuel Rail Pressure (FRP) Sensor Circuit Malfunction Description: The comprehensive component monitor (CCM) monitors the FRP sensor to the powertrain control module (PCM) for VREF voltage. The test fails when the VREF voltage from the PCM drops to a voltage less than a minimum calibrated value. Possible Causes:

• VREF open in harness.
• VREF open in sensor.
• Vacuum leaks.

Diagnostic Aids: Verify a VREF voltage between 4 and 6 volts. Application Key On Engine Off Key On Engine Running Continuous Memory Fuel rail pressure temperature (FRPT) sensor - GO to DD26 GO to DD26 Fuel rail pressure (FRP) sensor only - - GO to DD1 Fuel rail pressure (FRP) and fuel rail temperature (FRT) sensors - - GO to DD1


P0191 - Fuel Rail Pressure (FRP) Sensor Circuit Performance Description: The comprehensive component monitor (CCM) checks the FRP for acceptable fuel pressure. The test fails when the fuel pressure falls below or exceeds a minimum/maximum calibrated value for a calibrated period of time. Possible Causes:

• High fuel pressure.
• Low fuel pressure.
• Damaged FRP sensor.
• Excessive resistance in the circuit.
• Vacuum leaks.
• Low or no fuel.

Diagnostic Aids: A FRP PID value during key on engine running (KOER) of 138 kPa (20 psi) to 413 kPa (60 psi) is acceptable. Application Key On Engine Off Key On Engine Running Continuous Memory Fuel rail pressure temperature (FRPT) sensor GO to DD34 Fuel rail pressure (FRP) sensor only GO to DD9 Fuel rail pressure (FRP) and fuel rail temperature (FRT) sensors GO to DD9


P0192 - Fuel Rail Pressure (FRP) Sensor Circuit Low Input Description: The comprehensive component monitor (CCM) monitors the FRP sensor circuit to the powertrain control module (PCM) for low voltage. If voltage falls below a calibrated limit for a calibrated amount of time during testing, the test fails. Possible Causes:

• FRP signal shorted to SIG RTN or PWR GND.
• Damaged FRP sensor.

Diagnostic Aids: A FRP PID value during the key on engine off (KOEO) or key on engine running (KOER) less than 0.3 volt indicates a hard fault. Application Key On Engine Off Key On Engine Running Continuous Memory Fuel rail pressure temperature (FRPT) sensor GO to DD26 GO to DD26 GO to DD39 Fuel rail pressure (FRP) sensor only GO to DD1 GO to DD1 GO to DD14 Fuel rail pressure (FRP) and fuel rail temperature (FRT) sensors GO to DD1 GO to DD1 GO to DD14


P0193 - Fuel Rail Pressure (FRP) Sensor Circuit High Input Description: The comprehensive component monitor (CCM) monitors the FRP sensor circuit to the powertrain control module (PCM) for high voltage. If voltage exceeds a calibrated limit for a calibrated amount of time during testing, the test fails. Possible Causes:

• FRP signal shorted to VREF or VPWR.
• FRP signal open.
• Damaged FRP sensor.

Diagnostic Aids: An FRP signal high condition can be caused by any number of conditions, including a short on FRP signal to VREF, a more positive voltage level, an open FRP signal or signal return. The FRP signal line is pulled up by the PCM and VREF at the sensor, and down by the sensor through SIGRTN.

Fault Code Definition P0193

• Fuel Rail Pressure Sensor Circuit High Input

What does this mean?
The Powertrain Control Module (PCM) needs to know the fuel pressure at all times so it can effectively control the fuel injectors and deliver the optimal amount of fuel into the engine's combustion chambers for maximum power and economy while maintaining the lowest tailpipe emissions.
Code P0193
indicates that the signal from the Fuel Rail Pressure Sensor and/or its circuit is too high, indicating a fuel pressure condition that is abnormally high.

If you are talking about a trouble code for the pressure sensor, the sensor may be telling the computer the fuel pressure is too high. The sensor is mounted in the fuel rail on the engine.

Fuel Rail Pressure Sensor Circuit high input.
1. Unplug the negative battery terminal connector (black one, NOT red) from the battery and set aside. Doing this will also reset your check engine light as well.

2. Unplug the fuel pump fuse. Check owners manual for proper location in underhood fuse block.

3. Start vehicle and run it until it dies to relieve pressure.
4. Disconnect the electrical connector to the sensor on fuel rail.

5. Remove bolts to fuel rail pressure sensor.

6. Disconnect hose on back of Pressure Sensor.

7. Once everything is disconnected, pull straight up on sensor. Be sure to pull up with a little effort, it has a snug fit. Of note, you will see gasoline when you lift up the FRPS so be careful so as not to let debris fall in there.

8. Install new FRPS and reconnect hose and electrical connector.

9. Put the fuel pump fuse back in.

10. Reconnect negative battery terminal.

11. BEFORE YOU START THE VEHICLE, you need to prime it. Do this by cycling the key to the ON position and Off position several times for the fuel pressure to build back up . Do this 2-3 times then start your vehicle.
CHECK FOR LEAKS, TEST DRIVE FOR ABOUT 10 MILES OR SO AND BE SURE EVERYTHING IS OK AND CHECK ENGINE LIGHT DOES NOT RETURN.

Someone has no idea how to diagnose a ford,
I would say

PO 113--Intake Air Temp Circuit High Input
PO 191--Fuel Rail Pressure Sensor Circuit Range/Performance

I wouldn't be installing any parts, until you find the real issues
there,try a different shop or dealer

A fuel pump & cps sensor & give it back to you half
fixed
That was nice & typical of all the people that come here

code p 0193 refers to fuel rail pressure (FRP) sensor---high input===causes ---wiring short to positive ---FRP sensor

code p0358 refers to ignition coil H -primary/ secondary--circuit malfunction ===causes --wiring--ignition coil---ECM

What is too high? The specification for that vehicle is 35-70 Psi (2.4-4.8 kg/cm2)
What is the data reading on the Fuel Rail Pressure Transducer sensor?
What, exactly, are you trying to fix? Do you have rich oxygen sensor codes?

0191 is fuel rail pressure sensor circuit range/performance 0193 fuel rail sensor circuit high input 0652 sensor reference voltage b circuit low 0341 cam shaft position sensor a circuit range/performance (bank1 or single sensor) and 0069 map barometric pressure correlation
i hope that helps you some what
