What does p0332 mean on a GMC Sierra?
P0332 is a powertrain related OBD-II trouble code. It has the same meaning for the GMC Sierra as it would any other vehicle. By definition, P0332 means that the vehicles ECM/PCM is getting a signal that is lower than the defined operational range from the knock sensor (Sensor 2 | Bank 2).
What does the p0332 code on the knock sensor mean?
The powertrain control module (PCM) monitors engine “knocking” with the help of a knock sensor. When a certain amount of spark knock is detected, the module will retard ignition timing to prevent engine damage. What Does the P0332 Code Mean?
What is the DTC code for knock sensor 2?
Diagnostic trouble code (DTC) P0332 stands for “Knock Sensor 2 Circuit Low Input (Bank 2).” It belongs to a range of trouble codes that are triggered by a knock sensor malfunction ( P0325 to P0334). A P0332 code gets logged when the PCM receives a reading from the knock sensor that is lower than the voltage specified by the manufacturer.
Why is the knock sensor on my GMC Sierra not working?
It would be wise to start by taking a look at the wiring harness. P0332 is telling you that the ECM/PCM is getting a low signal from the knock sensor. When this happens the computer will operate as though it is getting no signal from the sensor at all. Check the wiring leading from the sensor and see if any of it has been damaged or frayed.
What does the p0332 code on knock sensor 2 mean?
If the knock sensor 2 circuit gives a low input signal, the PCM (powertrain control module) record a P0332 code and illuminate the Check Engine Light. What the P0332 code means. The knock sensor’s purpose is to signal to the PCM when the engine is pinging.

What is the diagnostic code for knock sensor 2?
P0332 is a diagnostic trouble code (DTC) for “Knock Sensor 2 Circuit Low Input (Bank 2)”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
Why does the PCM record a p0332 code?
If the knock sensor 2 circuit gives a low input signal, the PCM (powertrain control module) record a P0332 code and illuminate the Check Engine Light. The knock sensor’s purpose is to signal to the PCM when the engine is pinging.
