My 98 Impreza is throwing a code. P0325 - knock sensor 1 circuit malfunction bank 1 or 1 sensor. The check engine light came on 2 days ago and since then has gone off and come back on twice. Anyway I called a Subie Dealer near me and they said usually they just replace the sensor when this code comes up. So my 1st question is, is that true, that code doesn't signify anything but the fact that the sensor needs to be replaced? Question 2, where is this specific sensor located and is there anything special i have to do in order to put a new one in, is it just unplug, replace, replug???
thanks guys, you all rock
