Default Got a code 23(knock Sensor) and the engine is not knocking.

Got a civic hatch with GSR and it is flashing a code 23, from what i know the car is not knocking. Is there any other signs to tell if i really need a new knock sensor. I really don't want to by another one if i dont have too.

Please Help. Thank You!!

See if you get less knock with higher octane. Your ingition or cam timing could be slightly off.

Did you use "shielded wire" for the knock sensor, when you did the swap? That can cause EM interference to read as knock to the ECU...

Check to make sure it isn't loose or anything too.
