What is P0332 fault code and what does it mean? What is the Knock Sensor 2 circuit low input (Bank 2) malfunction description? How do you fix the P0332 fault code What are the symptoms and causes for the P0332 fault code
What is the P0332 fault code? What does it all mean?
If the powertrain control module (PCM) receives a voltage signal from the knock sensor 2 circuit that is lower than the manufacturer-specified voltage, it sets code P0332 and illuminates the check engine light.
The knock sensor reports vibrations and misfires from the engine cylinders to its PCM. The knock sensor’s job is to report low signals to the PCM so that the PCM can adjust the ignition timing and stop the engine from knocking. This could lead to higher engine emissions and other problems. The P0332 fault code is triggered if the knock sensor in bank 2 produces a low output voltage (probably lower than 0.5V).
Code P0332 could appear intermittently. Alternatively, the check engine light might be on all the time. Other knock sensor fault codes are P0326 and P0327.
What are the Possible Reasons for the P0332 Fault code?
- – Broken or defective knock sensor
- – A failure in the knock sensor circuit and its connectors
- – Very low fuel/air mixture
- – Any cooling system problem
- – Defective EGR system (exhaust gas regeneration)
What are the symptoms for P0332 Fault Codes?
Symptoms of the P0332 fault code are common. You should consult a licensed mechanic immediately if you experience any of the above symptoms. This will help to prevent serious engine problems.
- – Illumination for check engine lights
- Low engine performance
- – Increased fuel use
- – When you accelerate, engine makes a loud whistling sound
- – An increase in engine temperature during normal operating conditions
How to Fix the P0332 Fault Code
It is common to replace the knock sensor without fully investigating the problem. Sometimes the problem may be due to wiring or connector issues. The EGR or cooling system could also be responsible for the malfunction. It is not worth spending money to replace the knock sensor.
- – Test the knock sensor resistance
- – Replace frayed or damaged wires and connectors within the sensor circuit
- Ensure that the circuit and sensor are grounded properly
- – Replacing knock sensor
- – Checking for a fault with the EGR or cooling systems
- – You can replace or reprogram your PCM (rarely)
How serious is the P0332 Fault code?
Engine knock can have a serious impact on the engine’s ability run efficiently and cleanly. The PCM can’t get the right information from the knock sensor if it isn’t working properly. This could cause engine problems such as overheating, fuel efficiency reduction, or other issues.
