P0442 - Evaporative emission control system problem
P0336 - Code for a crank position sensor problem.
I'm not sure what you mean by asking what they look like.

Here are the specific code definitons:
P0336-Crankshaft Position Sensor A Circuit Range/Performance
P0442-Evaporative Emission Control System Leak Detected (small leak)
The first one indicates a bad crank position sensor. On a 3.1, I'm pretty sure sensor A is the one in the back of the block.
the second code is a leak in the evap system, that could be anything from a bad gas cap, to stuck vent valve, to cracked/broken vacuum line.
