Cayenne Turbo 955 Code P0327

[Spanky7081]

Good evening,

 

2004 Cayenne Turbo 112k Miles

 

I’m getting code P0327 still after replacing both knock sensors(since I was in there and only $28 each). Car goes into limp mode and boost is limited to .4.I checked wires and connections while I was under the intake manifold replacing the sensors and it looked great. Looks like others have had rodent damage to wires but mine were fine.

 

Any ideas!?

P0327 Knock Sensor, Bank 1 - Below Limit

 

Possible fault cause
- Open circuit, crimping fault or loose contact in sensor wiring and/or ground wire
- Short circuit to ground in sensor wire
- Corrosion or loose contact on plug connection
- Knock sensor loose
- Knock sensor faulty
- DME control module faulty

Must be DME issue then since everything else was checked during new sensor install. Would you agree?

Turns out it was a wiring issue to the knock sensor. High heat area caused insulation on wires to crack.
