P0386

DTC P0386, sometimes indicated as P038600 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the ignition system causing crankshaft position sensor b circuit range/performance.

The crankshaft position sensor (CPS) is an electronic device used in an internal combustion engine to track the position and speed of the crankshaft. The CPS is usually located near the front of the engine, in line with the crankshaft.
The P0386 code means that the CPS has detected a problem with the signal it is receiving from the crankshaft. This could be due to a wiring problem, a bad sensor, or a problem with the engine itself.
If you have this code, check the wiring to the CPS and the sensor itself for damage or corrosion. If everything looks good, have a mechanic check the engine for any problems that could be causing the sensor to malfunction.
