P1345 MINI Code - Misfire Cylinder 2 With Fuel Cut-off
Quick Answer
As part of the CARB/OBD regulations, the Engine Control Module (ECM) must determine if a misfire is occurring and also identify the specific cylinder(s) and the severity of the misfire event and whether it is emissions relevant or catalyst damaging. Common causes include Faulty Spark Plug, Faulty Ignition Coil, Intake vacuum leak. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1345 MINI Description
The misfire/engine roughness calculation is derived from the differences in the period duration (T) of individual increment gear segments. Each segment period consists of an angular range of 120° crank angle that starts 78° before Top Dead Center (TDC).
If the expected period duration is greater than the permissible value a misfire fault for the particular cylinder is stored in the fault memory of the ECM. Depending on the level of misfire rate measured the control unit will illuminate the "Service Engine Soon" light, may cutoff fuel to the particular cylinder and may switch lambda operation to open-loop. All misfire faults are weighted to determine if the misfire is emissions relevant or catalyst damaging.
What are the Possible Causes of the DTC P1345 MINI?
- Faulty Spark Plug
- Faulty Ignition Coil
- Intake vacuum leak
- Faulty Camshaft Position Sensor
- Ignition Coil harness is open or shorted
- Ignition Coil circuit poor electrical connection
