Coolant Temperature Sensor - engine coolant temperature sensor for the AJ-series 4.4L V8 and 4.2L supercharged V8 petrol engines.

The sensor is a thermistor exposed to engine coolant; its electrical resistance falls as coolant temperature rises. The engine control module reads this signal to set fuelling and ignition timing, control warm-up enrichment, switch the cooling fans and drive the temperature display.

A sensor that has drifted or failed can cause poor cold starting, raised fuel consumption, cooling fans running incorrectly and a stored engine management fault code.

Frequently asked questions

What does the LR000291G coolant temperature sensor do?
The LR000291G coolant temperature sensor measures engine coolant temperature and sends it to the ECU for fuelling and cooling control. On the 4.4 AJ petrol V8 it's mounted in the fuel rail area. Fits the Discovery 3, Range Rover L322 and Range Rover Sport L320.
Which models and engine does this sensor fit?
This coolant temperature sensor fits the Discovery 3 (2005-2009), Range Rover L322 and Range Rover Sport L320 with the 4.4 AJ petrol V8, plus the 4.2 supercharged V8 on the L322 and L320 Sport. Confirm your engine is one of these AJ V8 petrols.
What are the symptoms of a failed coolant temperature sensor?
A failed coolant temperature sensor typically causes poor cold starting, rough running, incorrect fan operation, or a temperature warning on the AJ V8. Because the ECU relies on its signal for fuelling, a faulty sensor can store fault codes and affect economy.
