p0192 and some sort of limp mode, please assist..
I'm about 1500 miles into a trip..
Coming over black mountain Friday eve, or around 350 miles into this leg, the truck was fine as can be.. strong, in fact.. nearing Knoxville, it dropped out of cruise control.. upon stopping for fuel, and re starting the truck a check light came on.. h&s tells me its a p0192..
I clear it and it instantly returns.. according to gauges there is no pressure at the rail, as In zero. But the engine runs fine.. the thing Is in some sort of limp mode, though, because the trans flares between gears and it will only allow me to apply maybe 30~40% throttle (otherwise, it behaves like a rev limited)..
So.. the pump is working or it wouldn't run at all.. I drove over 1k moles with it like this.. it didn't drink fuel excessively, and it was fine on power (stock power, or maybe slightly less) ... Once I got it to highway speeds, the only way to tell something was amiss was the lack of cruise control.. as soon as i cycle the key, the code returns, though..
I'm running an air dog 150.. what are the chances that thing has frozen up in the cold? The canister filters are exposed to wind and such, and its certainly been cold enough to do it.. from what I've read the sensor is a diaphragm type that measures passing fluid. If it is restricted due to freezing, dies this not make sense?
If not, what else could it be? Where would you guys start?
Any help deeply appreciated..
