Instead, the engine's temperature is primarily monitored by the Engine Coolant Temperature (ECT) sensor. This sensor is much more common and is typically located in the engine block or the intake manifold. The data from the ECT sensor provides the information the computer needs to control engine temperature and other related functions. While not directly a CHT sensor, the ECT sensor’s reading closely approximates the cylinder head temperature.
To find the ECT sensor on your 2003 Ford Explorer V8, you'll need to consult a repair manual specific to your vehicle's year, engine size (4.6L or 4.0L V8), and possibly even trim level. The manual will have diagrams showing its exact location. You can usually find these online or at an auto parts store.
Searching online for "2003 Ford Explorer V8 ECT sensor location" along with your specific engine size (4.6L or 4.0L) will also likely yield helpful images and information from forums or repair sites.
