i have the same issue. occurred also in quest.5 hrs labor, orig knock sensor can go for 300 so find on on a website much cheaper (40-70$) then also the gaskets have to be replaced once you open it up and coolant drained. while u r there you may as well replace back 3 injectors (# 1, 3 and 5) (approx 100 each). so u figure it out...expensive and common on this vehicle. u can also chk forums for reasons knock sensor is going off. bad struts, dist failure, oyg sensors, cat convertor. its a nightmare
