Cylinder Block Temperature Sensor
WARNING: This page is about a different car, the 2018 Land Rover Discovery Sport. 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 hole on the front side of the cylinder block, between the generator and the electric throttle.
The sensor is a Negative Temperature Coefficient (NTC) type sensor with a two pin connection. One pin receives a 5 V reference voltage from the Powertrain Control Module (PCM) and the second pin provides a signal feedback to the PCM.
