code 0480!!! i need to stop the fan!! Sign In

P0480 code---my fan it wont go off.... i have changed the relay, also i have changed the temperature control sensor..... but my problem is the fan keep running when i turn the engine off.... it keeps on until kill my battery... is ridiculous every time i get home or work i have to open the hood and disconnect the relay so i turn off the fan.... (i know is normal when you turn off your car the fan remains on for about a minute... but mine remains on)

any suggestions?

Your getting the PO480 because your pulling the relay out. Your probably going to need a scan tool to first look at the temperature reading and then look to see if the computer is requesting the fan on. I would expect your going to find a short to ground on the Dk green wire which goes to the PCM and is used to control the relay by applying ground to it. If it's shorted to ground, then the relay will never turn off.
