Fryedaddy Posted March 7, 2021 Share Posted March 7, 2021 Anybody have an idea of what this wire is? Is it supposed to be plugged up? Link to comment Share on other sites More sharing options...
Ωhm Posted March 7, 2021 Share Posted March 7, 2021 Should be shielded wire for the Knock Sensor (KS) signal. Can't tell from photo, but do two (2) wires go to the connector? Note tin foil type stuff wrap around wires, that 3rd wire should connect that shield to ground. Purpose is to prevent electromotive force (EMF) from outside sources riding on the KS signal wire causing a false reading. If you can read continuity to ground on that wire your good to go.
