Engine Coolant Temperature (ECT) sensor 2

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 2 is installed in the lower hose connector which attaches to the bottom of the electric thermostat. The input from this sensor is used for On-Board Diagnostic (OBD) diagnostics and, in conjunction with the input from ECT 1, to confirm that the electric thermostat is functional.

If there is an ECT 2 fault, the ECM illuminates the MIL on the second consecutive trip.
