Cylinder Block Temperature Sensor
WARNING: This page is about a different car, the 2019 Jaguar XF. However, it is still accessible from the selected car via links, so may be relevant.
The cylinder block temperature sensor is located in a threaded boss on the left side of the cylinder block, between the electric thermostat housing and the High Pressure (HP) fuel pump.
The sensor is a NTC sensor with a two pin connection; one pin receives a 5V reference voltage from the PCM and the second pin provides a signal feedback to the PCM.
