What is P0330 fault code? What is Knock Sensor 2 circuit malfunction (Bank 2)? How can you fix the P0330 error code? What are the causes and symptoms of the P0330 error code?
What is the P0330 fault code? What does it all mean?
The knock sensor monitors engine vibrations and misfires during ignition and combustion. It is usually attached directly to the engine block. It transmits a signal to either the vehicle’s PCM or computer via Bluetooth when it detects misfires in one of its cylinders. This information is used to prevent misfires, and adjust the ignition timing.
A piezoelectric crystal is the knock sensor. This crystal can generate AC voltage by vibrating. It converts changes of physical quantity into electric signals. This means that the knock sensor doesn’t get a reference voltage from a PCM, but creates its own voltage. There are two main types of knock sensor: the one used in older vehicles or the one used in modern vehicles.
Two knock sensors can be fitted to some vehicles. Fault code P0330 refers to the number 2 knock sensors. This sensor is located on the side where the number 2 engine cylinder is located. If this sensor detects too high or low input voltage, the PCM will save the P0330 fault code to its memory. It can lead to engine damage and more serious problems if this error code is not corrected.

How Serious Is the P0330 Fault Coding?
The fault code P0330 is not dangerous to the safety or driving ability of your vehicle. While driving, you may notice a slight decline in power and performance. It is a mistake to ignore the issue and leave it unattended. This will lead to more expensive repairs and serious issues in the future. It is best to get it fixed as soon possible.
