Temp Sensor Suits: Nissan Patrol GQ & GU with TD42 engines. Suits: Nissan Patrol GU with RD28 & ZD30 engines. Suits: Nissan Patrol GU with TB45 & TB48 engines. Suits: Nissan Patrol Y62 with VK56 Engine. 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. Please check the plug, as earlier GQ TD42 engines have a different plug and run a different sensor.
