Code P0190 2007 Ford Fusion Description
The FRP sensor is located on the fuel rail, and provides a feedback signal to indicate the fuel rail pressure to the Powertrain Control Module (PCM). The PCM uses the FRP signal to command the correct injector timing and pulse width for correct fuel delivery at all speed and load conditions. The FRP sensor, along with the fuel volume regulator (part of the fuel injection pump), form a closed loop fuel pressure control system. An electrically faulted FRP sensor results in the deactivation of the fuel injection pump. Fuel pressure to injectors is then provided only by the FP module. When the fuel injection pump is de-energized and the injectors are active, the fuel rail pressure is approximately 70 kPa (10 psi) lower than FP module pressure due to the pressure drop across the fuel injection pump. Thus, if the FP module pressure is 448 kPa (65 psi), then the fuel rail pressure would be approximately 379 kPa (55 psi) if the injectors are active.
What are the Possible Causes of the DTC P0190 2007 Ford Fusion?
- Low or no fuel
- Faulty Rail Pressure (FRP) Sensor
- FRP harness is open or shorted
- FRP circuit poor electrical connection
- Faulty Fuel Pump

Frequently Asked Questions about P0190 2007 Ford Fusion Code
1. What does the OBDII code P0190 mean on a 2007 Ford Fusion?
P0190 indicates a "Fuel Rail Pressure Sensor Circuit Malfunction," meaning the Engine Control Module (ECM) has detected an issue with the fuel rail pressure sensor's electrical circuit.
2. What are the common symptoms of code P0190 in a 2007 Ford Fusion?
Symptoms may include difficulty starting the engine, engine stalling, decreased fuel efficiency, rough idling, and a check engine light.
3. What causes the P0190 code to appear on a 2007 Ford Fusion?
Common causes include a faulty fuel rail pressure sensor, damaged or corroded wiring, loose electrical connections, or a malfunctioning ECM.
4. Can I drive my 2007 Ford Fusion with the P0190 code?
It is not recommended to drive the vehicle with this code active, as it can lead to poor engine performance and potential damage to the fuel system or engine.
5. How do I diagnose the P0190 code on a 2007 Ford Fusion?
Start by checking the wiring and connectors for the fuel rail pressure sensor, test the sensor's voltage with a multimeter, and use an OBDII scanner to monitor live fuel pressure data.
6. How can I fix the P0190 code on my 2007 Ford Fusion?
Repairs may include replacing the fuel rail pressure sensor, repairing or replacing damaged wiring or connectors, or reprogramming the ECM if necessary.
7. How much does it cost to repair a P0190 code on a 2007 Ford Fusion?
The cost varies depending on the issue, but replacing the fuel rail pressure sensor typically costs $100-$300, including parts and labor.
8. Can a clogged fuel filter cause the P0190 code on a 2007 Ford Fusion?
While a clogged fuel filter does not directly cause the P0190 code, it can lead to inconsistent fuel pressure, potentially triggering related issues.
9. How do I reset the P0190 code on my 2007 Ford Fusion after repairs?
You can reset the code by using an OBDII scanner to clear the error or disconnecting the battery for a few minutes, though the underlying issue must first be addressed.
10. Is the P0190 code specific to Ford vehicles?
No, the P0190 code is a generic OBDII code that can appear on many vehicles, but the diagnostic and repair process may vary by make and model.
