Default high fan speed

Hi All- new to the forum. Have an issue I am hoping one (or more) of you may shed some light on. My 2005 has 141k on it and it currently has an issue with the fan clutch- I replaced the clutch and it is still throwing a code for high fan speed. I also replaced the relays and checked the pins in the connectors. I am at a loss as to where to look next. The old clutch and the new clutch felt fairly close in resistance to turning.

Thanks
