DTC P0341
Camshaft Position (CMP) Sensor Performance

DTC P0440 Evaporative Emission (EVAP) System (problem or leak)

DTC P0452
Fuel Tank Pressure Sensor Circuit Low Voltage

the P0440 and P0452 most likely are related. a P0440 is most commonly caused by a loose gas cap(3 clicks minimum) if the gas cap is tight, read this-

from wolfman on saturnfans.com about the P0452

The pressure sensor is in the fuel tank. Part of the fuel pump module. Replacement requires removing the tank. (Sorry) in past instances I have found however that the sensor rarely fails. It is most likely (in order of probability)

1. Bad gas cap.
2. Loose rubber sleaves on filler pipe to tank junctions causing a vacuum leak
3. Bad/loose wiring to the sensor at the splice pack located under the carpet, driver's side trunk wheel well area.
4. Loose or bad hose connection at the carbon canister, CCPS (carbon canister purge solenoid) or tank vapor line at the tank.
5. HOLE in the gas tank. (Seen people drill right into the top of the gas tank on occasion when installing a stereo amp in the trunk area of the car)
