P1264 JEEP Meaning

The glow plugs are used to preheat the combustion chambers in order to achieve the ignition temperature required for the fuel-air mixture.
The glow plug consists of a housing with a female thread and an interference-fit rod. The heating element is integrated into the glow rod. It consists of a heating winding and a control winding connected in series.
When the glow plug system is switched "ON", a current of about 30 ampere flows to each glow plug. The heating winding heats the glow plug. The control winding increases its resistance as the temperature rises and limits the current to approximately 15-25 ampere. The glow plug is protected this way from overloads.
