26 is a quad driver failure, 41 is a cam sensor failure. I can give you a test procedure for 26 but for 41 you likely need to replace the magnet that is in the cam gear for the cam sensor pick-up.

you can take of the ground of the battery of the car for 30 minutes and the computer will reset. if you drive around without reseting the computer might figure it out after 30 miles.

You are off to a good start by testing the fans. Get a repair manual from your nearest autoparts store. I find them invaluable. Most temperature sensors can be tested with an Ohm meter. Or short the two wires together to trigger fans. If it has only one wire then ground it to the frame/body (negative side of battery). If none of that works (with ignition on / car off) then relay is bad. Also turning on the A/C should make the fans come on. Car does not have to be running, key in on position. This would eliminate bad relays or not.
