P0327 Code?
Got p0327 code today. Does this mean it is faulty or does it mean the motor is knocking. Was really cold tonight and probably making more boost than usual. Any ideas?

Reset the code, see if it comes back. This is a KS perfomrance related code and is hard to diagnose sometimes. But usually its a sensor going bad.
Below is a snipit from the manual
Phil
DTC P0327 or P0332
Circuit Description
The knock sensors (KS) produce an AC signal under all engine operating conditions. The powertrain control module (PCM) calculates the average voltage range of each KS signal. If the KS system is operating correctly, the PCM will monitor the KS voltage which is varying above and below an average voltage. If the PCM detects a KS 1 signal, or a KS 2 signal voltage, within an average voltage range, a DTC will be set. DTC P0327 refers to the front KS. DTC P0332 refers to the rear KS.
Conditions for Running the DTC
DTCs P0117, P0118, P0125, P1114, P1115, P1120, or P1121 are not set.
The engine speed is between 1,650-3,000 RPM.
The manifold absolute pressure (MAP) is less than 49 kPa (7.1 psi).
The engine coolant temperature (ECT) is more than 60°C (140°F).
The throttle angle is more than 0 percent.
The engine has been operating for more than 10 seconds.
The ignition voltage is more than 10 seconds.
Conditions for Setting the DTC
The PCM determines that this frequency is less than the expected amount for more than 9 seconds.
Action Taken When the DTC Sets
The control module illuminates the malfunction indicator lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails.
The control module records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the control module stores this information in the Failure Records. If the diagnostic reports a failure on the second consecutive ignition cycle, the control module records the operating conditions at the time of the failure. The control module writes the operating conditions to the Freeze Frame and updates the Failure Records.
