OBD-II DTC P0360 – Ignition Coil I Primary/Secondary Circuit Malfunction

DTC P0360 meaning

DTC P0360 refers to a malfunction in the ignition coil’s primary or secondary circuit. This code indicates that the Engine Control Module (ECM) has detected an issue with the ignition coil’s operation, which is crucial for the proper functioning of the engine. The ignition coil is responsible for converting the battery’s low voltage into the high voltage needed to create a spark in the spark plugs, igniting the air-fuel mixture in the engine cylinders.

Common symptoms associated with DTC P0360 may include:

  • Engine misfires
  • Rough idling
  • Decreased engine performance
  • Difficulty starting the engine
  • Illuminated check engine light
