Knock sensor testing
(1) Resistance test for knock sensor
Switch ignition "OFF", unplug the wire connector of knock sensor, test the
resistance between the wire terminal and the case of knock sensor with
"Resistance test" function, it shall be ∞(disconnected), and if it is 0Ω(conductive),
which means the knock sensor shall be replaced. For the magnetostriction
