P0141 & P0341

I have a 2001 Silo. Today my check engine light has came on. I took it to the Autozone to have the codes checked and it came back with P0141,P0341,P0141. Why it done the same code twice Idont know. Can anyone help me with the codes and what the problem might be. As of now the vehicle is running fine. Thanks

141 is the o2 heater circuit not working for the #2 sensor in bank one, 341 is the pcm is not seeing a cam sensor signal. Either the fuse is bad for o2 sensor or the sensor is bad, the cam sensor must be checked with a scope or a full scan is required.

The probable reason for the code showing up twice is one is a hard code and the other is pending. The O2 sensor heater is probably bad. For the cam sensor, you can see it if you look right behind and below the power steering pump. It sits right where you would notice an intake leak if you had one. When I did my lower intake manifold gaskets I noticed my cam sensor wiring was bare and about to come out of the sensor even though it had never been touched. You may want to see if you can see anything obvious first.

also the cam sensor is made of plastic and cracks on the end over time.

Would the vehicle be running rough or sluggish with these codes?

Would the Heater sensor make the vehicle hard to heat? Or is that something to do with the cooling system?

These codes have nothing to do with lack of heat. I assume you are refering to heat from the vents.
You might want to check you coolant level, also check for a lower intake/head gaskets for leaks.
