    What Does P0323 Mean?

    P0323 is a OBD II fault code that indicates that there is an issue with the Ignition/Distributor Engine Speed Input Circuit. This code is also commonly referred to as a crankshaft or camshaft position sensor error code. The Engine Control Module (ECM) has detected an issue with the the rotation speed or the position of the crankshaft or camshaft. The ECM receives an input from the crankshaft and camshaft position sensors based on the engine configuration and the year, make and model of the vehicle. The input is used to monitor the speed and position of the crankshaft and camshaft. Some automobiles also incorporate an ignition/distributor speed sensor that is monitored by the ECM. This information is used to adjust the ignition timing and the fuel settings to adapt to engine load variations and improve performance.
