Message	not when you have detonation? from fsm: the knock sensor is shorted or open. therefore, code 34 tells you to replace to sensor, harness, or clean the connections due to a short or open circuit (grounded or cut). you would see detonation as a retardation of timing after the knock sensor senses it and the ecu pulls timing, as verified with blazt program timing "gauge" or reading
