This sensor is on the later model GQ TD42 engines after August 1995 and all GU TD42 engines.
This sensors 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.
This sensor does not control the temperature reading on the dashboard
Please check the plug, as earlier GQ TD42 engines have a different plug and run a different sensor.
