Honda P0192-Fuel Pressure Sensor Circuit Low Voltage

Honda P0192 Fuel Pressure Sensor Circuit Low Voltage

Code P0192 Honda is DTC code indicating problem with the fuel rail pressure sensor circuit. Specifically p0192 indicates that voltage signal from fuel rail pressure sensor to engine control module is too high and outside of the expected range. This sensor is responsible for monitoring fuel pressure in the fuel rail and send corresponding voltage signal to the engine control module. This information is use by engine control module to control the fuel injection system and ensure that the engine is receiving correct amount of fuel.

Possible Causes Code P0192 Honda

1.Fuel rail pressure sensor may be faulty and sending wrong voltage signal to engine control module.

2.Fuel rail pressure sensor wiring or connector may have problem such as loose or corroded connection.

3.Faulty fuel pump as failing fuel pump may not deliver enough fuel pressure to the fuel rail causing fuel rail pressure sensor to report incorrect reading to engine control module.

4.Clogged fuel filter can cause fuel pressure to drop and sending incorrect reading from fuel rail pressure sensor.

5.Faulty fuel pressure regulator can cause fuel pressure to be too high or too low and causing fuel rail pressure sensor to send incorrect reading to the engine control module.

6.Failing engine control module unable to accurately process the voltage signal from fuel rail pressure sensor.

7.Other potential causes for p0192 include clogged fuel line, faulty fuel injector or issue with fuel system wiring or connectors.

Honda P0192 Possible Symptoms

1.The most common symptoms associated with p0192 is illumination of check engine light on the dashboard.

2.If fuel rail pressure sensor is not working properly the engine may have starting difficulty or may not start at all.

3.Faulty fuel rail pressure sensor can cause the engine to misfire or engine may run rough.

4.If fuel rail pressure sensor is sending incorrect reading to engine control module , engine may not be receiving correct amount of fuel resulting in poor performance of the engine.

5.If fuel rail pressure is sending incorrect reading to engine control module. Engine may be using more fuel than required resulting in reduced fuel economy.

6.In some acute condition engine may stall or shut off completely if fuel rail pressure sensor is not functioning properly.

How To Fix P0192 Honda

1.Inspect fuel pressure to ensure that it is within it specification limit, if it is not fuel filter or fuel pump may be faulty.

2.Inspect rail pressure sensor for damage or wear, replace the rail pressure sensor if necessary.

3.Check wiring and connectors of fuel rail pressure sensor for damage or corrosion repair or replace any damaged components.

4.Inspect fuel pressure regulator for proper functioning if found faulty replace it.

5.Inspect engine control module for any signs of damage or wear, replace it if necessary.

Notice

Its important to have the vehicle inspected and diagnosed by professional mechanic to find and resolve issue related with Honda P0192 for proper repair.
