Code P1352 Hyundai Description

The P1352 Hyundai code indicates that there is an issue with the #2 MF (Magnetic Field) signal line being open. In Hyundai vehicles, this code typically relates to a problem with the ignition coil or the wiring associated with it. The ignition coil is responsible for converting the low voltage from the battery into the high voltage needed to ignite the fuel in the combustion chamber. When the #2 MF signal line is open, it means that there is a break or interruption in the circuit that sends signals to the ignition coil, resulting in a lack of spark and potentially causing misfires or engine performance issues.
