Also there does not seem to be any knocking or unusual sounding noises... how ever this is the first ti e ive owned this motor , but i dont think its actually picking up a knock as the sensor code goes of even without cranking the engine...

Ok so im forced to try and replace the entire cable for the knock sensor from the ecu, can i use any type of cable ? I bought some auto electrical figure 8 cable (positve and negative next to each other) will this do?

Ok soooo yay i fixed it !!!!!!
What a stuff around!

After searching on the net and not getting 100 percent clear ideas on what to do i reached out to logic and try n see methods.

Heres what i did and found out...

The cable from ecu has to be shielded, this shielding has to be grounded to the chasis.
The power side of the shielded cable goes into the power side for the knock sensor,
the plug ( from ecu to knock sensor not the one from knock sensor)
holds the cables in via a small thin blue rubber seal in back of plug, this is not soldered or crimped.... so in my case i was going to re solder the wires as they were in 2 parts, instead i removed the short bit i had left on the plug by removing the rubber with a small thin screw driver then using pliers i pulled the wire from the plug, i spliced my wire from ecu put heatshrink over the shielded part so no contact with anything else,pull the blue rubber ring over the new cable, then folde
d and twisted my splice to make it thick,
then push it in the plug to make it hold in push the blue ring into the plug as far as it goes without braking it.

Then run a seperate cable from the negative end of the plug to the sensor grounding point of the ecu ( important wont work otherwise)


Thats it job done, make sure you get a good connection and it worked...


Thanks to everyone for your help

Good job and thanks for the info.

One last update on this
The shielded wire you will need is called rg 58cu its a shilded wire pretty much the exact same as the original.

Last thing i got the problem back after 2 days after trcing everything down making sure a solder didnt come undone i noticed the most anoying thing.... the actual plug on the ecu was wobbly and when touched or wobbled the slightests would throw out the knck sensor again... i chcked the plug nothing to fix just old... so i pushed the plug into the right position then the snsor ligt turned of and cable tied it so it wouldnt move.... just thought if any1 ever has this problem this is gd info... check the plug first!
