tsc; The 'Knock sensor' is designed to 'listen for pre-ignition' ping. Or, spark knock, if you will. Unfortunately, it can't distinguish if the 'knock' is from pre-ignition, rocker arms, rod or main bearings. Do you have ANY engine noises that it could be 'hearing'?

SW Washington A code 43 means there is a problem with the ability to adjust timing so the system is not operational.

Check the wiring harness that comes from the sensor around the front of the engine. I had one where the harness got moved and the serp belt cut thru the knock sensor wire.....
