Xadamx1 Posted March 8, 2012 Share Posted March 8, 2012 I have had the P0325 code on my Subie for some time. It's a 1997 Outback Legacy 2.5L. Anyway, this weekend I did some reading and read that relocating the sensor can stop this problem. I relocated it to the position they mentioned, I still have the problem. Do I need to buy a new sensor or is there anyway to just bypass the knock sensory entirely? Quote Link to comment Share on other sites More sharing options...
unibrook Posted March 8, 2012 Share Posted March 8, 2012 I just went ahead and replaced mine when I got the code on my 2001 Forester with about 105k on it at the time. Easily done, if you go that route. I dunno about bypassing it. Quote Link to comment Share on other sites More sharing options...
Mike104 Posted March 8, 2012 Share Posted March 8, 2012 Just replace it. You could try and disconnect/reconnect it but its probably shot. When you get the code the ECU sets the timing to a less than optimal setting to prevent knock thus giving you poor gas mileage. Quote Link to comment Share on other sites More sharing options...

Not only does the ECM retard your timing when it senses an actual knock , but if the ECM does not see the regular "noise"(normal engine operation) from the sensor, it will pull your timing to the max value. So you can't just remove it or even move it to another spot. Moving it may either give you no knock protection( because it won't pick knock up) or the ECM may pull timing because it doesn't the hear normal background noise.

bstone Posted March 8, 2012 Share Posted March 8, 2012 Just replace it and you'll be good. I've done it and it's not too bad. I ended up removing the throttle body, but you might have smaller hands. Quote Link to comment Share on other sites More sharing options...
