I've been getting this code alot lately and it interfears with my performance of the car.

I checked all the connections between the airfilter and and the throttle body and everything is a go.

Any Idea's????

I am going to go check the connection right now on the knock sensor.

 

DTC P0332 Knock Sensor (KS) 2 Circuit

Circuit Description

The Knock Sensor (KS) system detects engine detonation. The PCM retards the spark timing based on the signals from the knock sensors. The knock sensors produce an AC voltage. The knock sensor voltages are an input to the PCM. The amount of AC voltage produced is proportional to the amount of knock.

An operating engine produces a normal amount of engine mechanical vibration (noise). The knock sensors produce an AC voltage signal from this noise. When an engine operates, the PCM learns the minimum and maximum frequency of the noise the engine produces. When the PCM determines that this frequency is less than or greater than the expected amount, a knock sensor DTC will set.

Conditions for Running the DTC

The engine speed is between 1650 RPM and 3000 RPM.
The MAP is less than 49 kPa.
The engine coolant temperature is greater than 60°C (140°F).
The throttle angle is greater than the idle throttle angle.
The engine has been operating for longer than 20 seconds.
Conditions for Setting the DTC
The PCM determines that this frequency is less than or greater than the expected amount for less than 3.0 seconds.

Action Taken When the DTC Sets

The PCM illuminates the malfunction indicator lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails.
The PCM records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the PCM stores this information in the Failure Records. If the diagnostic reports a failure on the second consecutive ignition cycle, the PCM records the operating conditions at the time of the failure. The PCM writes the conditions to the Freeze Frame and updates the Failure Records.
Conditions for Clearing the MIL/DTC
The PCM turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
A last test failed, or current DTC, clears when the diagnostic runs and does not fail.
A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
Use a scan tool in order to clear the MIL and the DTC.
Diagnostic Aids


Diagnostic Aids

Inspect the knock sensor for proper installation. A knock sensor that is loose or over torqued may cause DTC P0327 to set.
The knock sensor jumper harness is located at the left rear of the intake manifold near the crankcase vent.
