Knock Sensor (KS)
CAUTION:
Knock Sensor (KS) connector terminals are gold plated to provide good conductivity and resistance to corrosion and high temperatures. Be careful not to damage terminals when probing with test equipment.
Ensure KS mounting bolt is tightened to 16 ft. lbs. (22 N.m). Check for poor connections, loose terminals, and open or shorted wires. See WIRING DIAGRAMS article.
