Glow Plug Controller

The Glow Plug Controller is a relay switch that controls the working of the glow plug in your vehicle's diesel engine. The glow plug is a device that is used to preheat the combustion chamber to a temperature that is hot enough to support fuel combustion. The glow plug controller switches the glow plug on and off when needed. When the ignition switch is turned to the "Wait to Start" position, the glow plug relay turns on the glow plug. The glow plug is kept on long enough to raise the temperature of the engine block. A temperature sensor sends a signal to the relay once the temperature reaches a certain level, and the relay disconnects the glow plug. The driver can now start the car by turning the ignition to the "On" position.

In some cases, the glow plug controller keeps the plug on even after the engine is started to keep the emission levels low. A faulty glow plug controller will fail to turn the glow plug on or off when needed. A relay switch that fails to turn on would prevent your engine from starting due to insufficient temperature in the combustion chamber, especially in cold weather. If the relay switch is stuck in the "on" position, it would cause the glow plug to burn out very quickly. A faulty glow plug controller should be replaced at the earliest.
