Unfortunately paid cash. Next morning truck did the same thing. I picked it up yesterday and it’s now running fine. Waiting for the trip cycle to set off the codes again. They told me now p0191 and p0193 are showing current. Stored b1201-20-IC. Intermittent FRP readings occur.

We replaced this and this and your truck is still the same.. you own us for the parts that didn't fix your truck.. not ! Replace the FPDM..not expensive and you can do it.. two bolts and a plug.

Po191 trouble.please help
I have 06 with 4.6 and I keep getting the p0191 code multiple times a day and I clear it with my programmer. It will idle funny sometimes when you start it up especially with the air conditioning on. I've replaced the fpdm a couple years ago and even tried a new one the other day to see if it made a difference and it didnt. I've also replaced the fuel rail pressure sensor. And makes no difference. The fuel pump is about 3 years old. I'm at a loss and dont know what to do next. Any help is greatly appreciated
