Just wanted to clarify: from what I gather, when you get a code 34, it means your ECU detects a short/open in the knock sensor circuit, e.g., your sensor is bad.
If your engine is actually knocking for some reason (and the knock sensor is functioning correctly and detects knock), the ECU will compensate by retarding the timing, up to 3000rpm at least.
If your sensor is bad and you're getting a code 34, you do need to change the sensor because your ECU is probably getting bad values and retarding your timing. Your car will probably feel sluggish until you replace the sensor.
Someone correct me if I'm wrong.
