hmmmmm.....
My truck is a 2001 ETC with an AT. I had an erratic idle problem and took it into the shop on Monday. The tech said he replaced the crank sensor and the repair ticket shows the same. Part number was 5080577AA. So, does anyone know if that part number is for a crank or a cam sensor? Whatever was replaced did the trick. The tach is VERY steady during idle now.
