quick knock sensor question

Post by haru182 »

hey guys, I am really sorry to do this but could some kind soul please figure something out for me? Basically I need to know what size hex wrench I need and approximatly how long of a ratchet extension I need in order to replace my knock sensor.

The long version of why, is that my car has been sitting an hour from nyc ( I drove here from chicago) and I saw it a few weeks ago and it had a bad knock sensor (lucky me). So I already ordered/received a new one but the next time I get to see my car I need to be able to drive it home. (I do not trust the house its at to have the proper tools). I have access to tools where I am now but I need to make sure I take the right ones with me when I go to replace the sensor/drive it home.

Thanks for any help!!

You can drive it home without the sensor installed.

Whenever you do replace it, have some duct tape and some magic fingers (those picker-upper tools with little claws) handy too.

You can duct tape the extension(s) and socket together to make sure they don't come apart. You use the magic fingers to pull the bolt and old sensor out, and to position the new sensor. You then tape the bolt very lightly to the socket so you can position it and tighten it.

The knock sensor TSB recommends 12" extension and a universal joint.
