Knock Sensor (KS)

KS is located on cylinder block. Sensor is tested by substitution or by manually generating a knock to ensure sensor will set a service code. Faults in sensor or circuit should set a service code. See QUICK TEST in TESTS W/CODES - EEC-IV article in the ENGINE PERFORMANCE section. If service code has not been set, see CIRCUIT TEST DG in TESTS W/CODES - EEC-IV article in the ENGINE PERFORMANCE section for additional sensor circuit testing procedures.
