Engine Coolant Temperature (ECT) sensor 1

WARNING: This page is about a different car, the 2018 Jaguar XE and 2017 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

The ECT 1 is installed in the heater manifold, at the rear of the Bank 1 cylinder head. The input from this sensor is used in calibration tables and by other systems.

If there is an ECT 1 fault, the PCM adopts an estimated coolant temperature. On the second consecutive trip with an ECT 1 fault, the PCM illuminates the Malfunction Indicator Lamp (MIL).
