What does trouble code p0332 on a knock sensor mean?
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?
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.
When does the p0332 code come back?
2002 Silverado 1500 2 wheel drive 5.3 120k miles codes p0332 2 times erase and they come back when driving around 60 mph. I have read that I would need to check the voltage but not sure were it would be located. any suggestions. recently drove into water at high speed did not flood.
What are the symptoms of a p0332 DTC?
You may notice drivability problems including fluctation engine RPM, a loss of power, and perhaps some hesitation. There may also be other symptoms. Potential causes for a P0332 DTC include (but are not limited to): The knock sensor is faulty and needs to be replaced There is a wiring open/short/fault in the knock sensor circuit

Why do I keep getting p0327 / p0332 error codes?
Since your battery was disconnected during this procedure, your P0327 / P0332 error code (s) should have been cleared. If something is still wrong, these codes will show up again rather quickly upon driving around. If you get the same codes again, you may have a wiring (or ECU) problem elsewhere.
Where are the knock sensors located on a GMC Truck?
How long will this take? Plan on 3-4 hours; shorter if things are relatively clean under your Intake Manifold. Where are the Knock Sensors (KS) located? GM, in their infinite wisdom, hid the sensor underneath the intake manifold.
What does trouble code p0332 mean on a Chevy Silverado?
Troubleshooting and solving a trouble code P0332 usually involves replacing the rear knock sensor. Before replacing the knock sensor (since this bad boy is located underneath the intake manifold), I recommend the following: Testing the internal resistance of the knock sensor (specification: 9.3 to 107 K Ohms). Checking for intake manifold leaks.
What does knock sensor 2 low circuit input ( Bank 2 ) mean?
Knock Sensor 2 Low Circuit Input (Bank 2) What Does P0332 Mean? Knock sensors are solely used for the purpose of sensing when your engine is “knocking,” or sensing when there is exploding in the air/fuel mixture in a way that delivers less power and can also damage the engine if prolonged.
When does the knock sensor get too low?
If the PCM or ECM receives a reading from the knock sensor that is too low, the P0332 trouble code is set. When this happens, the engine computer is not able to communicate effectively with the sensor to detect knocking problems.
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 does the p0332 code mean on a Chevy?
The P0332 code means that the Knock Sensor is not working properly. Problems with the knock sensor will not cause an engine performance problems. Replacing the knock sensor usually takes care of the problem. The cost to diagnose the P0332 CHEVROLET code is 1.0 hour of labor.
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 causes the knock sensor 2 circuit low?
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. This can result in higher emissions and other problems for the engine, as well. What causes the P0332 code?
