I have an 07 Suzuki SX4, had the PO327 code, After struggling to find the knock sensor (it's behind the engine, about 8 in. to left of alternator, then up a bit). Without taking the whole top of engine, I went from under the car, had to use my phone to take pictures to see it. It was in bad shape, I replace it with one from amazon. It was extremely difficult. The problem now is, I have a PO328 code, off and on. The engine light comes on, then goes off after a while. When I was looking for a new sensor, I found prices ranging from $10 to $290. I went with $10 because if it doesn't work, it's only $10. So, now I don't know if the problem is the cheap sensor, or it needs to be adjusted. From what I've read, if sensor too tight or too loose, might make a difference.
