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 G - EEC-IV TESTS W/CODES article in the ENGINE PERFORMANCE Section. If service code has not been set, see CIRCUIT TEST DG in G - EEC-IV TESTS W/CODES article in the ENGINE PERFORMANCE Section for additional sensor circuit testing procedures.
