This means the output voltage of a 2-bar map sensor with the key on and engine off is going to be somewhere around 2. It's both useful and empowering to know how to fix your own car. Just get them started. The knock has a different frequency than a regular burn in the cylinder. The knock limit, the point at which knock becomes excessive, depends upon fuel quality and engine, operating and environmental conditions. My question is, why would anyone go through all the trouble of replacing a knock sensor(s)on an LS430 with 'used' sensors. The microphone sound sensor, as the name says, detects sound. The sensor detects the brightness of an object and converts it to a numerical value and sends it to the NXT brick. This is the only sensor that makes its own voltage.
