Where is the the coolant temperature sensor on a 2000 Ford F-150 5.4 V8 4wd?

IT IS LOCATED ON THE INTAKE Because ECT (engine coolant temperature) sensor procedures vary depending upon their location, first locate the part. You may need to partially drain the engine coolant to prevent coolant spillage. * Disconnect the negative battery cable. * Unplug the ECT. * Then, unscrew it. * Reverse the removal procedures to install the new part. * Connect the negative battery cable to the battery.
