So i have already been through several posts related to my subject. Specifically regarding the flexalite electric fans. Trouble is, im not getting "soft" codes. My CEL lights up and here is what my banks IQ tells me: po480 fan clutch, po336 crankshaft pos ckp, po 483 fan speed. All these, several times while on a 1700 mile road trip. Last week it happened again and there were two additional po codes. I forget the numbers and my IQ said they were unknown.
Can anyone out there tell me how to fix this. Besides pulling the fan!
Seems to only happen on the highways@ 70 plus mph.
Additionally;
Fuel economy "overhead" was 22.7 for the trip. Mixed driving on the 10, crad canyon, Death Valley, lake isabella, Sequoia Natl, back to Oside.
Thanks for your feedback and experience.

 

I cant believe no one has any thing.
