At 22k miles I got this code. I couldn't find it on the internet. The dealer said it is a leaking air cleaner duct. They replaced it no charge. I'm hoping the light stays off.

Given that Diesel engines do not have an ignition system, I had no idea that they had a knock sensor.

Ok so dealer just called and told me a/the knock sensor failed. Not sure if/how that's related to P11DC ?

Tomko this motor does not have a knock sensor. checked all 8 pages of wiring diagrams for eng management at work yesterday an it is not there. the normal noise from this eng would drive a knock sensor crazy.

Thanks oilburner.

LulzT1 - I suggest that you tell your dealer that your bull$h!t sensor is working and that there is no knock sensor on this engine.
