My check engine light came on after i put freon in the car for the air condition. my friend has a computer that we hooked up to the car to find out what the problem was and this code came up P1490, what...

When you get that code it means that the computer isn't detecting the relay kicking in and starting the cooling fan.
In most cases replacing the relay for the fan will cure that problem and you can erase the code with scanner once the problem is repaired

Check engine light code 46? the guy that changed my oil said it was a loose bolt behind the engine or drive shaft.. I am not sure about the code number if I remember correctly.

Codes are usually 3 digits and will start with start with a letter...P(Powertrain), B (Body), C(Chassis) or U(undefined).
The majority of codes are power train codes and I looked at P046 and there is no such code.

The fastest way to find out the problem is go to an auto parts store and ask them to use their code scanner. They tpically will do this for free and then tell you what the codes mean.
