Default Stupid Knock Sensor - How to remove?

I've been having the same problem with the 86 Vette - L98. Getting a code thrown at me every so often. It's the knock sensor (43). I looked in the shop manual and see where it's suppose to be, but when I stand next to the motor I can't see how to get at it. :confused:

Any thoughts on my prob? Is this a simple procedure?

Thanks for any input! :cheers:

Did you try from under the car? Should be a piece of cake (at least on an LT1, not sure if L98's are different).

Bill,
If your knock sensor is in the same place as my 90, you need to
get to it from under the car right side.
1 Disconnect neg battery cable
2 Remove sensor shield
3 Remove wiring harness from sensor
4 Remove sensor from engine block
Make sure the engine is cold, let it sit over night.
You will get a little coolent but not much.
It is a very easy job. :cheers: :chevy

"You will get a little coolent but not much."

:U

Well, that didn't go as planned... I found it from the underside of the car - no problem. I took off the protective plate - no problem. Disconnected the wire to the knock sensor... Unscrewed the sensor, forgetting that some coolant will come out... but 1 & 1/2 gallons??? :U Had to rush for the bucket to catch it all.

Funny thing though - when I was getting ready to reconnect the plug to the sensor I noticed the pin inside was off center. Like it wasn't really connected right. So I straightened it out and reconnected it.

Can't try it right now because it's up on jack stands getting its tranny and OD fluids changed. :yesnod:

Yep, that sounds about right...All the coolant in that side of the engine, plus the pass head, and all coolant that connects to those parts...

(That hole is the block drain hole from previous years)

Ecklers makes a replacement wire harness for the Knock sensor; it's a worthwhile purchase...
