will the code P 0332 HC pull timing?
I've read so much on it, it gets confusing. Does this code show a problem in the knock system, or trigger a code because it's sensing knock? And if so, would throwing this code send the pc into going into a safe mode? Car keeps throwing it every now and then and it feels turdy

It triggers a code I believe, when mine did it, I replaced both knock sensors and the pigtail wiring connector that connects them both to the rest of the car as well as the oil plugs in the bottom of the wells they sit in, it's usually oil infiltration from the bottom or water from the top that does them in. Your supposed to RTV around the plug that covers the sensor after replacement.

The PCM is not seeing what it is expecting. It will not default to reduced timing. See below.

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 normally, the PCM should monitor the KS voltage varying above and below calculated average voltage. If the PCM detects a KS-1 signal or a KS-2 signal voltage within the calculated average range, a DTC will be set. DTC P0327 refers to the front knock sensor. DTC P0332 refers to the rear knock sensor.
CONDITIONS FOR RUNNING THE DTC
DTCs P0117, P0118, P0121, P0122, P0123, P0125, P1114, P1115, P1121 or P1122 are not set.
The minimum noise level must be learned. The minimum noise level is learned when the following conditions are met:
The ECT must be greater than 60°C (140°F ).
The engine RPM is between 475-975 for 10 seconds .
Engine speed is between 1500 RPM and 3,000 RPM .
Map is less than 49 kPa .
Engine coolant temperature (ECT) is more than 60°C (140°F ).
Throttle angle is more than 0 percent .
Engine run time is more than 10 seconds .
Ignition voltage is more than 10 volts .
CONDITIONS FOR SETTING THE DTC
The PCM determines that this signal 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.
CONDITIONS FOR CLEARING THE MIL/DTC
The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
Clear the MIL and the DTC with a scan tool.
DIAGNOSTIC AIDS
IMPORTANT: If the knock sensor is dropped, it must be replaced.
Check the knock sensor for proper installation. A knock sensor that is loose or over torqued may cause the DTC to set.
If DTCs P0327 and P0332 are set at the same time, inspect for poor connections at the KS harness jumper, located at the left rear side of the intake manifold.
For an intermittent, refer to Intermittent Conditions. See: Powertrain Management\Computers and Control Systems\Testing and Inspection\Initial Inspection and Diagnostic Overview\Diagnostic Strategies\Intermittent Conditions
TEST DESCRIPTION
Steps 1-6
Steps 7-13
The numbers below refer to the step numbers on the diagnostic table.
This verifies the malfunction is present.
This test will isolate the knock sensor from the rest of the circuit.
Tapping on the engine block will simulate an engine knock.
