P0314
Single Cylinder Misfire (Cylinder not Specified)
DTC P0314, sometimes indicated as P031400 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 single cylinder misfire (cylinder not specified).
The P0314 code means that the PCM has detected a misfire in one of the engine's cylinders. The code doesn't specify which cylinder is misfiring, so the cause could be anything from a bad plug or coil pack to a bad injector or wiring problem.
The first step in diagnosing the problem is to check for any obvious problems like a broken wire or connector, a leaky injector, or a cracked coil pack. If no obvious problems are found, then the next step is to do a diagnostic scan of the engine to see which cylinder is misfiring.
If the problem is a bad plug or coil pack, then the simplest solution is to replace them. If the problem is a bad injector, then the injector may need to be replaced or cleaned. If the problem is wiring or electrical, then the problem may need to be diagnosed and repaired.
