What Does P0330 Mean? The P0330 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. engine code P0330P0330 fixobd P0330dtc P0330obd code P0330obd2 P0330P0330 car codediagnostic code P0330car code P0330check engine code P0330fehlercode P0330P0330 fiatcodigo P0330codigo falla P0330P0330 kody b??dówcodigo de falla P0330 What are the common causes of P0330 ? Since the knock sensor is responsible for making the PCM aware of unexpected engine noises (primarily caused by an incorrect air/fuel mixture that leads to abnormal cylinder detonation), this code is often the reaction to another more serious problem. If other drivability codes are present, diagnose and repair those before attempting to diagnose this code. If the engine is running smoothly and quietly, and the code persists, the most likely cause is a faulty knock sensor. Frayed or broken wiring, corroded wiring and connectors, or connectors that are unplugged are also strong candidates. Some applications locate the knock sensor near the starter and the sensor connector is often broken during starter replacement. How do you troubleshoot P0330 ? While fuel economy was increased, acceleration was seriously compromised, and the loss of engine vacuum led to a dangerous loss of braking assist when the P0330 code system was in four-cylinder mode. In addition to these issues, while the company proposed a hydraulically controlled system that could be switched from within the car, the version they implemented had to be manually changed in the engine compartment using hand tools.
