Code P0192 2011 Ford Fusion Description

The FRP sensor is a diaphragm strain gauge device. The FRP sensor measures the pressure difference between the fuel rail and atmospheric pressure. The FRP sensor nominal output varies between 0.5 and 4.5 volts, with 0.5 volts corresponding to 0 MPa (0 psi) gauge and 4.5 volts corresponding to 26 MPa (3771 psi) gauge. The sensor can read vacuums and may lower the output voltage to slightly below 0.5 volts. This condition is normal and is usually the case after several hours of cold soak before the vehicle dome light is turned on. The FP module is energized at the same time the dome light is commanded on. A disabled or malfunctioning dome light does not affect the FP module control.
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.

Frequently Asked Questions about P0192 2011 Ford Fusion Code

What does the OBDII code P0192 mean for a 2011 Ford Fusion?

P0192 indicates that the fuel rail pressure sensor circuit is reading a low input, which means the Engine Control Module (ECM) is not receiving the expected voltage from the fuel rail pressure sensor.

What are common symptoms of the P0192 code?

Common symptoms include poor engine performance, rough idling, stalling, decreased fuel efficiency, and the check engine light illuminating.

What could cause the P0192 code to trigger?

Potential causes include a faulty fuel rail pressure sensor, damaged wiring or electrical connectors, a bad ECM, or issues with the fuel system such as low fuel pressure.

How can I diagnose a P0192 code?

To diagnose the P0192 code, check the fuel rail pressure sensor and its wiring for any damage, test the sensor's output voltage with a multimeter, and ensure the fuel system is operating correctly.

What are the potential effects of ignoring the P0192 code?

Ignoring the P0192 code can lead to poor engine performance, potential engine damage, decreased fuel efficiency, and could result in further trouble codes being triggered.

How can I fix the P0192 code?

Fixing the P0192 code typically involves inspecting and repairing any damaged wiring or connectors, replacing the fuel rail pressure sensor if it's faulty, and ensuring proper fuel system operation.

Is it safe to drive with the P0192 code?

While it may be possible to drive with the P0192 code, it is not recommended as it can lead to performance issues and potential engine damage over time.

Can I clear the P0192 code without fixing the problem?

You can clear the code using an OBDII scanner, but the code will likely return if the underlying issue is not resolved.

What is the average cost to repair the P0192 issue?

Repair costs can vary widely depending on the cause, but replacing the fuel rail pressure sensor typically ranges from $100 to $300, including parts and labor.
