Coolant Temperature Sensor threads into the engine coolant circuit and reports coolant temperature to the instrument and engine management systems.

Its resistance varies with temperature, producing the signal used to drive the temperature gauge and inform fuelling. The green colour code identifies this sensor's calibration, used on late 300 TDi and V8 applications.

Frequently asked questions

What does the AMR1425 temperature sensor do?

The AMR1425 is a coolant temperature sensor that threads into the engine coolant circuit and reports temperature to the gauge and engine management. Its resistance varies with temperature to drive the signal. The green colour code identifies the calibration used on late 300TDi and V8 applications.

Why does the colour code matter on this temperature sensor?

The green colour code identifies this sensor's specific calibration, used on late 300TDi and V8 applications. Land Rover used different colour-coded sensors with different resistance curves, so fitting the wrong colour can give inaccurate gauge readings. Match the green code to your application before ordering.

What are the signs the coolant temperature sensor is failing?

A failing coolant temperature sensor typically shows as an erratic or stuck temperature gauge, poor cold-start running, or fuelling problems on engine-managed V8s. The sensor's resistance can drift or go open-circuit with age. On the 300TDi the usual symptom is a gauge that reads wrong or doesn't move.

Which Land Rovers does the AMR1425 fit?

The AMR1425 fits the 300TDi Land Rover Defender, Discovery 1 (2.0 petrol, 300TDi and V8), Range Rover Classic (300TDi and V8) and Range Rover P38 V8 (1995-2002). It's the green-calibration sensor for these late applications, so confirm your engine matches before ordering.
