This wiring loom plug connects directly to the blue Engine Coolant Temperature (ECU) sensor on your engine. This sensor is critical, feeding temperature data to the Engine Control Unit (ECU) to manage everything from glow plug timing on diesels to the air/fuel mixture on petrol engines.
This sensor is for the temp of the engine to tell the glow plugs when to stop glowing on Diesel Engines, and on Petrol engines is gives the temperature to the ECU.
It is common for this plug to have the wiring pulled out of it, it gets broken when being unplugged, and they deteriorate from Heat and then get a poor connection or sometimes the clip is broken, and they won't stay plugged in.
This can cause various running faults
