The ECT sensor is located at the right end of the engine on the coolant outlet housing.

When the ignition switch is turned to Start and the starter motor is turning, the indicator light should come on, indicating a good bulb.

For the throttle body temperature sensor, remove the air cleaner, disconnect throttle cables, remove the accelerator cable bracket, unplug the electrical connector from the sensor, remove the sensor, apply heat transfer compound, install the sensor securely, and reverse the steps for reinstallation.

To replace the engine coolant temperature (ECT) sensor, start by partially draining the cooling system. Then, disconnect the cable from the negative battery terminal. For 2015 and earlier models with 3.6L V6, 3.7L V6, and 4.7L VB engines, disconnect the electrical connector from the ECT sensor and carefully unscrew it from the intake manifold. Wrap the threads of the ECT sensor with Teflon sealing tape before installing it. For 2016 and later 3.6L V6 engines, remove the air filter housing and disconnect the electrical connector from the coolant temperature sensor. Depress the locking tab on the bottom of the ECT sensor, rotate it counterclockwise, and pull it from the housing. Insert the ECT sensor into the housing, rotate it clockwise, and ensure the locking tab is against the stop. For Hemi engines, remove the drivebelt and unbolt the air conditioning compressor to access the ECT sensor. Disconnect the electrical connector and carefully unscrew the ECT sensor from the intake manifold. Wrap the threads of the ECT sensor with Teflon sealing tape before installing it. Finally, refill the cooling system.

The coolant temperature indicator system consists of a light or temperature gauge on the instrument panel and a coolant temperature sending unit on the engine.

The Engine Coolant Temperature (ECT) sensor, which also functions as the coolant temperature sending unit, provides information to the Powertrain Control Module (PCM).
