Code P1344 Audi Description
The diagnostic trouble code (DTC) P1344 for Audi vehicles indicates a problem with the ignition coil output stage 2 short to B+. This code typically points to an issue with the ignition coil or its related components. The ignition coil is responsible for converting the low voltage from the battery into the high voltage needed to create a spark at the spark plugs, igniting the air-fuel mixture in the engine cylinders. When the ignition coil output stage 2 is shorted to B+, it means that there is an abnormal electrical connection between the ignition coil output stage 2 circuit and the positive battery terminal (B+).
Common Causes of P1344 Audi
- Faulty ignition coil
