What does P0327 Knock Sensor 1 Circuit Bank 1 or Single Sensor code me

[skala57]

Hello Everyone!

I just ran a diagnostic test on my 2005 Cayenne S with my durametric tool and I came up with the following 2 codes....

P0327Knock Sensor 1 Circuit Bank 1 or Single Sensor - Value below lower limit value, test conditions are not-completed, fault is currently active and is not causing a DTC light

907Load management operat. on vehicle electrical sys./DME control module - No additional fault status available, test conditions are not-completed, fault is currently active and is not causing a DTC light

Anybody know what this is all about? I cleared all codes and will be running a test again tomorrow night after I get back from work. All your help is greatly appreciated.

See if the codes return or if they were just ghost codes. It recently came to light that some Cayenne's came equipped with a DME from a different manufacturer (Siemens if memory serves) that cause some weird diagnostics problems with the Durametric software, so you might want to check with Durametric as I understand they have a beta software version that offers a work around for these issues on vehicles equipped this DME.

Ok, sounds good. I'll check on that later on today... I'll post the results... Thanks JFP

Sorry to bring this thread back, I know its a little old. But I'm still getting the "p0327 Knock sensor fault code on my Cayenne. There were some other codes that popped up as well but thats all do to my cluster and PCM2 not communicating cause I upgraded to the Kenwood DNN990 Head unit, which by the way ROCK'S! This is what I first received upon start up....

p0327 Knock Sensor 1 Circuit Bank 1 or single Sensor - Value below lower limit value, test conditions are not completed, fault is currently active and is not causing a DTC Light....

p1116 Value below lower limit value, test conditions are not completed, fault is not currently active and is not causing DTC Light....

So I went and earsed all the fault codes.... Took it for a long drive, came back and all codes were still gone...

Next morning, started the Cayenne up and plugged in the Durametric, long and behold the p1116 was gone but the p0327 was back. So this only comes upon cold start up. Do I need to change Knock Sensors? All your help is greatly appreciated. Thanks!
