P0190 FRP Sensor Signal Low
 

Just started to get this error code. Anyone have any suggestions how to correct this? Spark plugs possibly be a culprit?

Nope, the spark plugs have no idea what the fuel pressure is. The fuel rail on the drivers side has a sensor with a wire harness clipped to it and that is the sensor that is bad here. You could try testing the pressure in the rails on the passenger side with a gauge and hook it to the valve under the black cap but likely the sensor. I have a spare if you need to buy a good one at a better price than your local dealer but that is were I would start.

Skylark, thanks for the help buddy.

I got around to changing the plugs today and checked all my hoses for a possible leak. The grommet or rubber seal on one of the pieces to the CAI was pretty bad. I think this is the Intake Air sensor? Yes? no? I took some tape and sealed it shut and went for a quick spin. She was back to her ole throughbred self again. I dont know what the part is called its right after the mass air meter. Plugs werent that bad for my noobie self.

Damn it, went for a ride today and got the code again. So I am looking to replace the Fuel Rail Pressure Sensor?
