im having trouble viewing the links since im on my work computer and it doesnt have a .pdf reader and im not allowed to download stuff on here.
i can change the knock sensor for $130. installed and all
im putting in my downpipe as soon as i get my FWI from wbodystore

 

 

DTC P0327 or P0332

Circuit Description
The knock sensors (KS) produce an AC signal when specific frequencies are detected. When the engine operates, the powertrain control module (PCM) learns a minimum and maximum frequency of noise of normal engine operation. The KS system monitors both knock sensors in order to determine if knock is present. If the KS system determines that excessive knock is present, the PCM retards the spark timing based on the signals from the KS system. The PCM then retards the timing until no knock is present. When the PCM detects a frequency that is less than or more than a defined range, DTC P0327 will set for a failure in KS 1 which is located on bank 1 on the drivers side of the engine or DTC P0332 will set for a failure in KS 2 which is located on bank 2 on the passenger side of the engine.


Conditions for Running the DTC

Conditions for Setting the DTC
The PCM determines that this frequency is less than or more than the expected amount for 3 seconds or more.


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.

Conditions for Clearing the MIL/DTC

Diagnostic Aids
Inspect the KS for proper installation. A KS that is loose or over torqued may cause either DTC to set.

For an intermittent, refer to Intermittent Conditions .

the question i have right now is
if i buy a tuned PCM from zzp, will the Upgraded Gearing fix my gear ratio thing?
