Coolant Temperature Sensor mounted in the cylinder head coolant gallery, part of the engine cooling and engine management system.

The sensor is a thermistor whose resistance varies with coolant temperature. The engine control module reads this signal to set fuelling and ignition timing during warm-up, to control the cooling fan and thermostat, and to drive the temperature gauge and overheat warning.

Used across the Ingenium engine family, covering the 1.5L three-cylinder, 2.0L four-cylinder and 3.0L six-cylinder petrol and diesel units.

A degraded sensor commonly shows as erratic or implausible temperature readings, poor cold-start running and raised fuel consumption, or a cooling fan that runs constantly.

Frequently asked questions

What does the coolant temperature sensor do?
The coolant temperature sensor measures engine coolant temperature and feeds it to the ECU for fuelling, cooling fan and gauge control. It typically threads into the cylinder head or coolant housing on Ingenium AJ200 and AJ20 engines, covering 2.0L four-cylinder and 3.0L six-cylinder petrol and diesel.
Which Land Rovers does this sensor fit?
This coolant sensor fits Ingenium-engined Land Rovers including the Range Rover Evoque L538 and L551, Range Rover L405, Range Rover Sport L494, Discovery Sport, Discovery 5, Velar and New Defender L663. It's a cylinder-head coolant sensor shared across the 2.0L and 3.0L Ingenium range.
What are the signs of a failing coolant temperature sensor?
A failing coolant temperature sensor typically triggers the engine warning light, erratic temperature gauge readings, poor cold starting or higher fuel use. Because the ECU relies on its signal for fuelling and fan control, a faulty sensor can cause running issues even when the cooling system is healthy.
Can I replace the coolant temperature sensor myself?
Replacing the coolant temperature sensor is usually a straightforward job with basic hand tools, though the system typically needs partial draining and the connector releasing. Confirm your engine is an Ingenium 2.0L or 3.0L unit before ordering, as the sensor is specific to this family.
