Title: Knock Sensor Repair
Post by: Jimbob on 07 July 2009, 09:09:40

Knock sensor 1 wire is badly grazed, been fine for a while, now getting frequent errors on it, so need to fix it.

Now this is a screened cable, can I just cut and join the cable & screening and reinsulate, or do I have to maintain screening around the fix, if so how?

No need to maintain the screening around a short repair section in this case

I've repaired one of these before, worked fine. Just used small, medium and large heat shrink to make sure it was watertight.

Might I add, someone else fitted it and routed the cable next the exhaust fanimold!  ;D

Sorry to dive in on your thread boyz, but when the Knock Sensor has been either broken or chaffed through this puts on the EML right?

code 16 (bank 1/3/5) or 17 (2/4/6)

eml may not come on until revs get up a bit

The one I am thinking about was trapped behind the aux belt tensioner so crushed flat, but it didn't put on the EML light...
I fitted a Brand New Vx Knock Sensor which was routed properly not caught anywhere to find when the ignition was turned on the EML came on with like you say a code 16.

Very puzzled why with a broken knock sensor the EML didn't come on but when it was replaced with a new one the EMl did come on :-?

its an intermittant EML in this case.

Will have a look when I have a few hours ahead of me, access is not good, the fix is at the depth of the metal pipe that runs across the front.
