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.
How does the knock sensor work on a Chevy Silverado?
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.
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.
What does p0332 mean on a Chevy Silverado?
P0332 is a powertrain related OBD-II trouble code. It has the same meaning for the Chevy Silverado 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).
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.
Why is the knock sensor on my Chevy Silverado not working?
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.
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.
