I just pulled code 65 off my odo and looked in my book and couldn't find anything. I'm getting ready for a NY State inspection and the check engine light cannot be on or you'll fail. So I needed to get this fixed before the end of the month. After that unneeded explanation the sensor is a A/C shut off switch if you turn the front wheels fast or all the way. while I haven;'t changed in yet, I think its going to be an easy fix. I have no idea on the price though!! Just follow the fluid lines from the PS resevoir and there is a pig tail hanging out and the sensor is on the other end. As told by my mechanic that I must go to in times like these.
Oh I too have a 97 SE 2.5!
