The green and black test wires you need are under the drivers dash, not in the passenger footwell. Read here (ya wee lassie)

lol cheers it came up with 22 knock senser thanks mate

 

So the next question is, is it a faulty 'knock sensor' or is it detecting 'knock???

 

well the check engine light comes on and stays on wen warm however it has an tendency to go off an on wen it feels like it lol

 

As far as i can understand it is the sensor at fault, from what i have read there is no ECU code for 'actual knock', hence the use of det cans i suppose

Plenty on ebay, but what the quality is like i have no idea. All the lambda's i had off there where $h1t

Perhaps someone can advise

 

thanx mate
