P1441 Chevrolet EVAP System Flow During Non-Purge Condition OBDII Engine Light Trouble Code | Engine-Codes.com
P1641 Chevrolet FC Relay 1 Control Circuit OBDII Engine Light Trouble Code | Engine-Codes.com
P01412 - not a valid code, P0141 maybe??

 

its p0412 sorry added an extra 1 in there

what parts do i need to replace most of that stuff is latin to me sorry

 

P1441 Gas tank is loosing pressure, try a new gas cap first, purge solenoid second, tank pressure sensor third, check fuel system for leaks.

P1641 Primary radiator fan not coming on, check fan relay, control wiring between relay and PCM, make sure relay is getting 12 volt from battery, check wiring from relay to fan motor, check fan motor (straight wire fan to battery & see if it turns).

P0412 AIR pump not working:
Faulty Air Pump (check fuse)
Air bypass solenoid harness is open or shorted, bad connection in solenoid circuit.

A wiring diagram for your car would be very helpful in order to check the electrical stuff.

 

Ok thanks I know the fan problem the PO did a weird wireing job and took the relay out. I'll check the other stuff best I can.
