Re: p0191 bolletin service

What engine do you have? This is for a 3.0. It's probably the same though. Post the engine size.
Code P0190-Fuel pressure sensor is outside the normal operating range of 0.2 to 4.8 volts. Use the engine off and running self tests. If the code does not show up, it is an intermittent code. The pressure reading signals are over 50 PSI (3.4 volts)- CNG only 80 psi (1.70 volts), or under 70 PSI (4.5
volts)- CNG only 150 psi (4.5 volts). Use a voltmeter to compare actual gas pressure to the indications of the pressure sensor. This code is usually set by missing or low 5 volt reference.
