your CRX should have a knock sensor so if your ECU has the knock PCB in it and knock is enabled in the ECU then you should have no problem

if yor ECU has knock disabled then you should still have no problem.

if your ECU has knock enabled and your knock sensor is faulty then you will get the engine lamp on with code 23 registered inthe ECU

what problem are you actually having ? engine lamp on ? code 23 in ECU ?

if you have knock enabled in the ECU and no knock sensor your ECU will need to be modified to disable the knock sensor. ( PM me as I can do this for you )
