Signal Too High - Intermittent Fault

Signal too high. Intermittent fault

Checking connectors and wiring
Check the signal cable between knock sensor (KS) terminal #1 and control module #A46 (#A46). Check the ground lead between knock sensor (KS) terminal #2 and control module terminal #A64 (#B4). Check for an intermittent short-circuit to supply voltage.
Check that the knock sensor (KS) is tightened to the correct torque.

Hint: The diagnostic trouble code (DTC) may be caused by a worn engine. Start the engine and listen for noise.

Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).
