What is the bank 2 knock sensor?
The knock sensor’s purpose is to signal to the PCM when the engine is pinging. If the PCM is receiving a reading from the knock sensor that is too low, it will not be able to accurately send the appropriate signal of a ping, and the PCM will not be able to correct the problem.
What does trouble code p0332 on a knock sensor mean?
A trouble code P0332: Knock Sensor No. 2 Circuit Problem usually tells you that the rear knock sensor has failed. In this tutorial I’ll explain what this trouble code means. I’ll also talk about some of the tests you can perform to find its cause. NOTE: The knock sensor is also known as the detonation sensor. What Does Trouble Code P0332 Mean?
When does the bank 2 knock sensor activate?
P0332 Code activates when the bank 2 knock sensor isn’t sending a signal to the engine computer. The P0332 OBD2 code activates when the bank 2 knock sensor isn’t sending a signal to the engine computer.
What causes a p0332 trouble code on a GMC Sierra?
What Causes A P0332 Trouble Code? In the majority of cases, a bad rear knock sensor is the cause of the P0332 trouble code lighting up the check engine light on your Chevrolet Silverado (Suburban, Tahoe) GMC Sierra (Yukon, Yukon XL). The 4.8L, 5.3L, and 6.0L engines are notorious for rear knock sensor failure from corrosion due to moisture.
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.
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.
Why is my knock sensor on Bank 2 low?
If your knock sensor on Bank #2 is generating a low output voltage (perhaps under 0.5V), then it will trigger a P0332 DTC. This P0332 code may show up intermittently or the Service Engine light may be lit constantly.
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 GMC Sierra?
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). Clearing this code typically requires a new knock sensor or correcting an issue within the wiring harness.
