What does knock sensor circuit low mean?
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 causes low voltage on knock sensor?
Diagnostic trouble code (DTC) P0327 stands for “Knock Sensor 1 Circuit Low Input (Bank 1 or Single Sensor).” It is triggered when the powertrain control module (PCM) detects very low voltage readings from your vehicle’s primary knock sensor circuit.
What is a knock sensor 2 circuit low input?
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). Without proper readings from the knock sensor, the PCM cannot accurately alter ignition timing to prevent engine knocking.
What causes code P0332?
When trouble code P0332 is set, the Power Control Module (PCM) has received a reading from knock sensor 2 in Bank 2 that is too low, and it will not be able to accurately send a ping to correct a problem.
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.
What does trouble code p0332 mean on a Honda Accord?
The powertrain control module (PCM) or engine control module (ECM) monitors the readings from the knock sensors, both to detect knocks and to ensure the sensors are operating properly. If the PCM or ECM receives a reading from the knock sensor that is too low, the P0332 trouble code is set.
