It may have come unplugged maybe?

I had the same problem, check the back of the engine, thats where its located

what one is it mate?

behind the inlet mani?

no from memory you will have to get under the car to see it properly, its right at the back of the engine iirc.

i was getting code 52, and checked the knock sensor and the wiring had come loose

[ollie ryan]

well the engine comes out next week so will check it all then

and what if its not loose?

can you just replace the sensor?
