bratman18 Posted April 10, 2009 Share Posted April 10, 2009 can any one post a pic where the knock sensor is at on my 91 legacy non turbo. i just cant find it.:-\ thanks for the help. I don't have a pic, but if you're looking from the front of the engine, it is just in back of and to the right of the throttle body. It is way down in there on top of the lock. It can be a pain to change!! It has either a white or green plug on it. Link to comment Share on other sites More sharing options...

GeneralDisorder Posted April 10, 2009 Share Posted April 10, 2009 It has either a white or green plug on it. For a 91 it would be white, or grey if it's been replaced with the upgraded version that doesn't crack. You'll need a 12mm socket, wobbly, and a 6" or longer extension bar to reach it. It's basically under the driver's side of the intake manifold. And this is the older gen forum - your legacy is a new gen - you should not be posting here.

rtcaravan Posted April 11, 2009 Author Share Posted April 11, 2009 thanks i didn't know that would be a newer gen vehicle but i'll post their now. going to the junk yard to find one sat. Link to comment Share on other sites More sharing options...
GeneralDisorder Posted April 11, 2009 Share Posted April 11, 2009 You are much better off getting one from the dealer - they are $50, difficult to access, and most used ones are also bad. They replaced the original knock sensors with a new version because they have a high likelyhood of cracking. GD Link to comment Share on other sites More sharing options...
rtcaravan Posted April 12, 2009 Author Share Posted April 12, 2009 i'll do that the one i found at the yard was cracked also. didn't think it was hard to pull off. thought it was very easy with no wobble needed. but i'll check the dealer. thanks Link to comment Share on other sites More sharing options...
Spiffy Posted April 12, 2009 Share Posted April 12, 2009 You are much better off getting one from the dealer - they are $50 I agree... you don't know what type of shape a used one is in... they're not THAT difficult to access, but they're in a tricky spot... especially considering there's a wire attached... things can get twisty... you can do it with a wrench, but expect a lot of short wrench throws... also, when you go to the dealer they can give you a print-out showing exactly where it is on your vehicle... very handy... sometimes I go to the dealer just for a print-out... --Spiffy Link to comment Share on other sites More sharing options...
GeneralDisorder Posted April 12, 2009 Share Posted April 12, 2009 thought it was very easy with no wobble needed. but i'll check the dealer. thanks Yes - it's quite possible that would be the case with the non-turbo's. My 91 SS is a pain the in a$$ to get to because of the additional plumbing and the water tank for the turbo. I haven't had to replace one on a non-turbo so I simply didn't think about it being any different (the sensor's are the same). Thanks for pointing that out. In fact mine is so difficult to access that I didn't put it back in the same location. I found another threaded boss that's easier to access and installed it there instead. Doesn't make any difference apparently. Other's on the legacycentral board have moved them as well. GD Link to comment Share on other sites More sharing options...
rtcaravan Posted April 14, 2009 Author Share Posted April 14, 2009 never got to see a turbo set up other than wrx's. ya wouldn't matter where it was mounted on the block as long as it can detect a knock. i could see the turbos being harder to get to.
