02silverpathy Posted March 26, 2005 Share Posted March 26, 2005 Anybody here replaced their faulty knock sensor?? was it hard? did you notice a gas mpg difference? did your truck run different? i have a fear of messing up the intake manifold gaskets...is this really a legit concern??

lewisnc100 Posted March 28, 2005 Share Posted March 28, 2005 I get the P0325 Knock Sensor Circuit Malfunction everytime I check. I would bet a very large percentage of 96+ Pathfinder owners have this same error code but don't know it since it does not trigger the CEL. I think the fact that it does not trigger the light says a lot about whether you need to change it. Also I've checked mine at the subharness connector with Nissan steps, and it passes. I don't plan on changing mine since I have no pinging and my MPG is as good today as when I drove it home in 1996. Link to comment Share on other sites More sharing options...
