  • DTC P0334 stands for “Knock Sensor 2 Circuit Intermittent (Bank 2),” and this is logged when the PCM detects an unusual signal from knock sensor 2.
  • Code P0334 is often caused by a failed knock sensor, defective wiring, or an internal engine malfunction.
  • The most common symptoms of code P0334 include a lit check engine light, poor engine performance, and acceleration issues.

Your vehicle has a number of sensors that all work together to ensure your engine and all other components are functioning as they should. One of these sensors is called a knock sensor. The knock sensor is vital to maintaining the proper operation of your engine.

P0334 is a genetic trouble code related to a fault in this sensor. Know more about it through this article.

What Does the P0334 Code Mean?

The knock sensor is vital to maintaining the proper operation of your engine.

Diagnostic trouble code (DTC) P0334 stands for “Knock Sensor 2 Circuit Intermittent Bank 2.” The code is set once the powertrain control module (PCM) doesn’t receive the right signal from the knock sensor located in Bank 2.

The knock sensor generates a low amount of electricity while the engine is running.   A code P0334 will be stored if the PCM detects an unusual signal from knock sensor 2.

Note: The definition of code P0334 might be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.
