Knock Sensor reading
I took out my knock sensor and measured it with a ohmmeter. Connected both leads to each terminal and I got .555 reading. Connected one lead to the 2nd terminal and the other to ground and got no reading at all. Is my ks bad? I never got any codes for this but there is performance loss. Any suggestions?
Thanks...

If you don't have code 0304, your knock sensor is ok. To check it you can use an ohm meter. One lead to ground, the other lead to one of the pins on the KS cable. One pin should gives about 550K ohm, the other pin should give infinite reading (no continuity). To have an idea of how bad the car performance is with a bad sensor, you can simply unplug the KS and take a test drive. The ECU should give 0304 code, and the car would be pretty sluggish. Don't forget to clear ECU code after you reattach the KS.
