EMERGENCY! Question about knock sensor.
I recently replaced my spark plugs and started noticing a slight jerk the car would do every 1-2 minutes while in either drive or reverse. I went down to Nissan and after putting the car up on the computer they have determined I need a new knock sensor and are replacing it as we speak. My question is what would make a knock sensor go bad or need it to be replaced? Also, what harm would be done if I were to continue driving or have driven with a bad knock sensor. Thank You, David.

The KS has nothing to do with your jerk. You have a misfire on a cylinder. Could be a bad plug or a coil pack starting to go bad. Give it some time and I'm sure your ECU will throw another code.

definately a misfire
ITs not your knock sensor. the dealer is ripping you off. Check to see if a spark plug boot around a plug is ripped. That's what my problem was. The car would jerk and skip because a spark plug boot was ripped. The ignition coil was also weak. Tell the dealership they have no idea what there doing because replacing the knock sensor won't fix our problem!!

If You would of told me this last week, you could of saved me hours of my own time working on this and lots of money. I rather would have donated a few hundred to this site rather then give it away to some scheming mechanic. I hope your right I will get it fixed tommorow, I will sleep in excitment today!

if the boot is ripped or torn, the dealer will try to sell you a whole new ignition coil because you can't just buy the boot from the dealer. The coils are around $70 depending on the dealer. You could do what I did buy a boot from autozone and retrofit it, mine works great. If not buy the whole coil and it will come with a new boot. or buy the ignition coil from autozone and do the job yourself. It's really easy.
