Engine Coolant Temperature Sensor

The Engine Coolant Temperature Sensor is located on top RF of engine intake manifold.

NOTE: In some applications of the 4.6L engine, the Cylinder Head Temperature (CHT) sensor provides the signal used by the Powertrain Control Module (PCM) in place of the Coolant Temperature Sensor (CTS) for functions such as, but not limited to, activating the electric cooling fans.
