quick question about gsr obd1

i wanted to know does my 94 gsr has a knock sensor because im getting code 23 (knock Sensor) i have a p72, the only reason im asking is because i've heard that some engines dont have it especially if there OBD1

replace the knock sensor if its bad, if its not the sensor check the wiring going from the ECU to the sensor. Its a red/blue wire btw, sensor is on the back of the block.
