Cylinder Head Temperature Sensor
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 cylinder head temperature sensor is located in a threaded boss in the front of the cylinder head, adjacent to the oil filter housing and the cylinder head water outlet pipe.
The sensor is a Negative Temperature Coefficient (NTC) thermistor with a two pin connection. One pin receives a 5 V reference voltage from the PCM and the second pin provides a signal feedback to the PCM.
