knock sensor question
Re: knock sensor question (1.5boosted)
It's because DOHC VTEC ECUs detect the knock sensor.
The knock sensor detects minute, high-frequency vibrations cause by pinging (or detonation). Once the pinging is detect, the sensor sends voltage signals to the ECU, then the ECU retards timing to stop the detonation.

Re: knock sensor question (1.5boosted)
You do not need a knock sensor for a P28 ECU, as it has no knock sensor capability. With a knock sensor capable ECU (i.e. P72), the knock sensor will trigger the ECU to retard timing if knocking is detected. This typically happens when non-premium fuel is used.

So the one wire sensor sends voltage signals? Where is it getting voltage from? Do the high-frequency vibrations cause voltage?
