{"product_id":"sensor-temperature-183742","title":"Sensor - Temperature for Discovery 3 (2005 – 2009) In Thermostat Housing – 4603183","description":"\u003cp\u003eThis is a coolant temperature sensor located in the thermostat housing, designed to monitor engine coolant temperature and relay real-time data to the ECU on 4.4 AJ V8 and 4.2 V8 Supercharged petrol engines. The ECU uses this signal to regulate fuel trim, ignition timing, and cooling fan operation. A faulty sensor can cause erratic temperature gauge readings, poor cold-start fuelling, increased emissions, or the engine running rich due to the ECU defaulting to a cold-engine map.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eMounts directly in the thermostat housing - no relocation or adaptation required\u003c\/li\u003e\n\u003cli\u003eSupplies coolant temperature data to the engine management system via a variable resistance signal\u003c\/li\u003e\n\u003cli\u003eOEM-specification replacement matching original fitment for Discovery 3, Range Rover, and Range Rover Sport applications\u003c\/li\u003e\n\u003cli\u003eInspect the wiring connector and housing seal for damage or coolant weeping when replacing this sensor\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\n\u003cp\u003eFits Discovery 3 (2005–2009) 4.4 AJ V8, Range Rover (2002–2009) 4.2 V8 Supercharged and 4.4 AJ V8 (to VIN 6A000001), and Range Rover Sport (2005–2009) 4.2 V8 Supercharged and 4.4 AJ V8.\u003c\/p\u003e\n\u003cp\u003eNot sure about fitment?
