What Does P0386 Code Mean?

    OBD-II Code P0386 is defined as a Crankshaft Position Sensor "B" Circuit Range/Performance

This provides a critical data signal used by the Powertrain Control Module (PCM) to control Ignition Spark Timing and Fuel Delivery. This sensor may be built into the distributor on older vehicles. When the PCM detects an irregular signal or no signal, it will set code P0386.
