Code P0198

[dnifong]

2008, 112k. stock and orginal.

motor shut off at idle, 25 mph, coming into a curve. almost wrecked. check engine light came on. found a P0194 code. cleared it, truck ran good, but now is doing it again.

question. "fuel rail pressure sensor circuit intermittent." does that mean there is a circuit problem "electricial, or sensor" or does that mean there is a problem with the fuel pressure?

where is the sensor located? how much time to change.

What are other possible causes?

thanks, dale
