Checking Wiring And Connectors
Check the knock sensor (KS) connector. Check for contact resistance and oxidation.
Check the signal cable between knock sensor (KS) terminal #1 and control module terminal #A46 (#A46). Check the ground lead between knock sensor (KS) terminal #2 and control module terminal #A64 (#B4). Check for an open-circuit. Check for a short-circuit to ground.
Check that the knock sensor (KS) is tightened to the correct torque.
Remedy as necessary.
