Code P0192 2010 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 P0192 2010 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 P0192 2010 Ford Fusion Code
1. What are the common symptoms of OBDII code P0192 in a 2010 Ford Fusion?
The common symptoms of OBDII code P0192 in a 2010 Ford Fusion include poor engine performance, rough idling, decreased fuel efficiency, and in some cases, the vehicle may even go into limp mode.
2. What causes the Fuel Rail Pressure Sensor Circuit Low Input code (P0192) in a 2010 Ford Fusion?
The P0192 code in a 2010 Ford Fusion is usually triggered by a faulty fuel rail pressure sensor, damaged wiring or connectors related to the sensor, low fuel pressure, or issues with the fuel pump.
3. How can I diagnose the Fuel Rail Pressure Sensor Circuit Low Input code (P0192) in my 2010 Ford Fusion?
To diagnose the P0192 code in a 2010 Ford Fusion, you can use an OBDII scanner to read the code and check the fuel rail pressure sensor's voltage readings. Inspect the sensor, wiring, and connectors for any visible damage.
4. Can I continue driving my 2010 Ford Fusion with OBDII code P0192 (Fuel Rail Pressure Sensor Circuit Low Input)?
It is not recommended to drive your 2010 Ford Fusion with the P0192 code present, as it can lead to poor engine performance and potential damage. It's best to address the issue promptly to avoid further complications.
5. How do I repair the Fuel Rail Pressure Sensor Circuit Low Input code (P0192) in a 2010 Ford Fusion?
To repair the P0192 code in a 2010 Ford Fusion, you may need to replace the fuel rail pressure sensor, repair or replace damaged wiring or connectors, check and correct the fuel pressure, and ensure the fuel pump is functioning properly.
6. Can a dirty fuel filter cause OBDII code P0192 in a 2010 Ford Fusion?
While a dirty fuel filter can affect fuel pressure, it is not a common cause of the P0192 code. However, it's a good practice to regularly maintain and replace the fuel filter as part of your vehicle's maintenance routine.
7. Will resetting the OBDII code P0192 in a 2010 Ford Fusion make it go away permanently?
Resetting the P0192 code in a 2010 Ford Fusion may temporarily clear the code, but if the underlying issue causing the code is not addressed, it is likely to reappear. It's important to diagnose and fix the root cause of the problem.
8. Is it possible for a loose gas cap to trigger the OBDII code P0192 in a 2010 Ford Fusion?
A loose gas cap is unlikely to trigger the P0192 code specifically, as this code is related to fuel rail pressure sensor circuit low input. However, it's always a good idea to ensure your gas cap is securely tightened to prevent other issues.
