Details of the p0384 OBD Code
Code P0384 relates to a problem with the crankshaft position sensor circuit.
OBD code P0384 means that a problem has been detected in the crankshaft position sensor circuit.
This code is triggered by the Engine Control Module (ECM) when it detects an erratic signal from the crankshaft position sensor.
The crankshaft position sensor is responsible for monitoring the position and speed of the crankshaft in the engine.
It provides crucial data to the ECM for ignition timing and fuel injection control.
When the sensor or its circuit malfunctions, it can lead to drivability issues and poor engine performance.
Mechanic’s Tech Notes
