My code on the 2005 ford mustang said that my fuel rail pressure sensor A Circuit


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. 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

Where is fuel pressure sensor at cant find it


Tank pressure sensor? Tank pressure sensor is in the fuel pump it on tank, it shouldn't have a fuel pressure sensor, it will have a fuel pressure regulator on the return line off the fuel rail

P0191 Ford - Fuel Rail Pressure Sensor Circuit Range/Performance P0191 Ford Description
The Fuel Rail Pressure (FRP) sensor is a diaphragm strain gauge device in which resistance changes with pressure. The electrical resistance of a strain gauge increases as pressure increases, and the resistance decreases as the pressure decreases. The varying resistance affects the voltage drop across the sensor terminals and provides electrical signal to the Powertrain Control Module (PCM) corresponding to pressure.
Strain gauge type sensors are consider passive sensors. A passive sensor is connected to a voltage divider network so that varying the resistance of the passive sensor causes a variation in total current flow.
Voltage that is dropped across a fixed resistor in series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor.
The FRP sensor measures the pressure of the fuel near the fuel injectors. This signal is used by the PCM to adjust the fuel injector pulse width and meter fuel to each combustion cylinder.

- Engine will not start Possible causes - High fuel pressure
- Low fuel pressure
- Damaged FRP sensor (most common)
- Excessive resistance in the circuit
- Low or no fuel
- Wiring harness connector of the fuel pressure sensor
- Fuel Rail Pressure Sensor
- Vacuum leaks
- Fuel leaking causing loss of pressure

What is the codes means po452 and po453


Hi,

The codes indicate a problem with the fuel tank pressure sensor. One code is for no volts, the other is for high volts. Without a scanner hooked up to monitor. I have to go with you have a bad fuel tank pressure sensor. this is an emissions control sensor. the tank is pressurized and the sensor monitors it for leaks etc. the tank must come out as it is mounted on top of fuel pump module

REMOVAL PROCEDURE

  1. Raise the vehicle.
  2. Remove the fuel tank. Refer to Fuel Tank .
  3. Remove the fuel tank vapor pressure sensor electrical connector.
  4. Remove the fuel tank pressure sensor.
INSTALLATION PROCEDURE
  1. Install the fuel tank vapor pressure sensor.
  2. Install the fuel tank vapor pressure sensor electrical connector.
  3. Install the fuel tank. Refer to Fuel Tank .
  4. Lower the vehicle.
Thanks.
