The sensor for the fan is mounted on the fuel rail and the fan cools the fuel rail to prevent vapor locking.

If this what you are talking about maybe I can dig up and image of it a little later.

what would cause the 81,82 codes to pop up? where do they get the signals from? i know 81 says TAD solenoid circuit failure or electro-drive fan failure or intake air control valve circuit failure. 82 is TAB solenoid circuit failure or electro-drive fan failure or supercharger bypass solenoid circuit failure.i don't have a supercharger,so thats ruled out.i now know where the TAD,RAB are,and what they look like.what does the electro-drive fan(s) look like?any and all info would be great.

Not sure where you are getting your information but an 81 & 82 are:
Service Codes 81 and 82 indicate that voltage output for Air Management solenoid(s) did not change when activated.

Possible causes:
--Solenoid circuits shorted to power.
--Solenoid circuits open or grounded.
--Solenoid resistance out of range.
--Damaged processor.

thanks again subford, i don't have a electro- drive fan.i've got the good old motor driven fan.i thought it may have been a fan in a different place or something.
