Just read my codes, the odometer displayed "P0191" which is apparently "Fuel Rail Pressure Sensor Circuit Performance" -?

I looked it up here http://www.autotap.com/codes.asp, is this the right place to find this code, it appears to be a generic OBDII code?

My friggin' code scanner did not pick this up, cycling the key 3 times and watching the odometer displayed it.

Question:

Has anyone had this and and got it fixed?

FYI: My check engine light is not on.

Thanks,
Eric

 

My truck had this code when new. I had just read about cycling the key 3 times, that's how I found it. The dealer had never seen it before and called Cummins about it. The paperwork I got from them says " rationality due to A/C high pressure switch wire rubbing on low pressure line. Insulated & rerouted wiring, OK at this time." They cleared it and it has never come back in over 17K miles...........Robert

 

Got it after I installed an edge ez and made a few WOT blasts. The next morning upon startup, the code would be there. Took the dealer to clear it, they said they wanted to replace the sensor and star wanted the old one. I didnt want to wait 4 days without the truck for them to receive the sensor. Figured out the box was for an 04, not 04.5 and sent it back. The code has never been back. Good luck.
