Codes..Need help please!

[Cummnzpowr]

On an 05' 6-speed 4x4,3500 seems like it is revving irratically at idle and looses fuel pressure rapidly engine codes come up as "0341". "0335,&"0336" can anyone tell me what these are? thank you . .

341= Camshaft Sensor Performance/rationality

335= Crankshaft Position Sensor Circut

336= Crankshaft Position Sensor Performance

Thanks Digger... he just had the truck pressure washed in the engine compartment. . it might have fouled it up or moved it.
