I have a check engine light on, on a 97 Pontiac Sunfire 2.4 Twin Cam... whats wrong?

[j.balde@att.net]

The check engine light has been on for awhile, the code is: P0480 Cooling Fan 1 Control Circuit Malfunction

I replaced the Coolant temp sensor, the coolant relay, and the fan and fan motor. I don't know what else it could be. Maybe the Thermostat? I don't' know. Anyone else know what else it may be? or possibly how to solve it?
Well basically, right now, I have it hooked up to a toggle switch thats the only reason why it doesn't overheat. If I didn't then yes, the car would overheat cause the fan would not run at all.

check your iat sensor...inlet air temp sensor...mine was bad and when my fans did go on, they stayed on so long to cool the engine (but with a messed up sensor the comp was reading it as hot) that my battery would die...so ya, check your iat sensor...or just go to an auto zone and ask for the scanner and hook it up...sounds like your sensor thought
