This is all new to me, so please forgive me if it all seems basic. I am trying to use my multimeter to diagnose error code P0330. I am having difficulty reading the FSM. I am trying to figure which pins I need to touch to measure the ohms. Also what is "body connector" Thank you ahead of time, and please forgive me if my ignorance is profound. I am trying to determine if the connector, harness, or knock sensor is causing the code.
