What Does P0331 Mean? Knock sensor 2, on engine bank 2, is designed to detect engine knocks or pings. This two-wire sensor sends a signal to the PCM to inform it of any instances of knocks or pings and how severe they may be. This input on normal knocks and pings allows the PCM to predict engine pre-detonation and account for it to predict knock trends and slow spark timing as necessary. If a knock or ping is too loud or too far out of the ordinary, the P0331 code will be saved, and the Check Engine light or MIL (Malfunction Indicator Light) will be illuminated. engine code P0331P0331 fixobd P0331dtc P0331obd code P0331obd2 P0331P0331 car codediagnostic code P0331car code P0331check engine code P0331fehlercode P0331P0331 fiatcodigo P0331codigo falla P0331P0331 kody b??dówcodigo de falla P0331 What are the common causes of P0331 ? To sum things up, the common causes for code P0331 are as follows: Failed knock sensor Fault in the knock sensor circuit Failed PCM How do you troubleshoot P0331 ? If the engine displays a miss and there wasn't a code, determine which cylinder is misfiring. If the exhaust manifold is visible, spay or pour a small amount of water on each cylinder exhaust port. Water will evaporate immediately on good cylinders and slowly on the missing cylinder. If this can't be accomplished pull the plugs and check the condition. With the valve disconnected, the red voltmeter lead should be attached to the IMRC valve power wire and the black voltmeter lead connected to ground. Now, clear the codes and test-drive the vehicle to see if the code is reset.
