Fault code 52.

[Duff]

Engine managment light came on yesterday. Did a diagnostics test there and it gave me code 52. no knock sesnsor signal input in to ECM. Any ideas on how to fix this?

Cheers.

If its not the wireing its the sensor.. do u have a rough tune buddy? or perhaps have a map set for a particcular type of fuel & uv used another?

easy mistake, but i can assure u for the 4e knock sensor to go its no coincidence..

The is mapped on Emanage blue but it still needs to be fine tuned as its running slightly rich. Would this cause it to knock?
