Ford F7DZ-10884-AA Sender Assembly - Temperature

You can Select Your Vehicle to check if F7DZ-10884-AA fits your vehicle.

If an overheating indication occurs, the coolant level in the system should be checked. Additionally, the wiring between the light or gauge and the sending unit should be ensured secure, and all fuses should be intact.

On SOHC four-cylinder engines, the sending unit for the gauge or light is threaded into the driver's side of the engine block, at the rear, just below the cylinder head.

When diagnosing the Engine Coolant Temperature (ECT) sensor, thorough testing is crucial before attributing driveability issues to the sensor. Similar to the IAT sensor, the ECT sensor, a thermistor, experiences resistance changes with temperature fluctuations. Positioned in the engine cooling system near the thermostat housing, it monitors coolant temperature, enabling the PCM to calculate the engine operating temperature. Circuit faults in the ECT sensor can trigger trouble codes, and issues may lie in wiring, connections, or the sensor itself. Some engines feature two nearly identical coolant temperature sensor units-one for the instrument panel temperature gauge and the other for the Electronic Engine Control (EEC) system. Disconnecting the ECT sensor and using an ohmmeter reveals resistance values, approximately 40,500 ohms at 65 degrees F and lower resistance at operating temperature. Confirming correct resistance, check for reference voltage, aiming for an open-circuit voltage around 5 volts from the PCM to the sensor connector. When replacing the sensor, wait for engine cooldown, wrap threads with Teflon sealing tape to prevent leakage, disconnect the electrical connector, unscrew the old ECT sensor, install the new sensor promptly, secure it tightly, reconnect the electrical connector, and check coolant levels, adding if necessary. Finally, start the engine, allow it to reach normal operating temperature, and inspect for coolant leaks, checking the expansion tank's coolant level after the engine has warmed up and cooled down.

To minimize coolant loss during this procedure.

It may be possible to access the sender with the thermostat housing removed.

After replacing the ECT sensor, start the engine and allow it to reach normal operating temperature. Then, inspect for coolant leaks and check the coolant level in the expansion tank after the engine has warmed up and cooled down.

Camshaft Position (CMP) sensor replacement involves disconnecting the battery, detaching the electrical connector, removing the sensor, and aligning the new one correctly.

The air conditioning clutch control involves PCM control of the compressor clutch. If the air conditioning does not function, you should check relays and switches. To test, remove the relay and bridge the battery feed and compressor clutch terminals.

After installing the replacement sending unit, you should check the coolant level to ensure it is at the appropriate level.

The two engine coolant temperature senders are generally referred to as the sending unit and the sensor.

If the indicator light does not glow when the ignition switch is turned on, the circuit should be tested. This can be done by grounding the wire to the sending unit while the ignition is on. If the gauge deflects full scale or the light comes on, the sending unit should be replaced.

I am showing part number F5RZ-10884-B for the water temperature sender for this vin, but unfortunately it is discontinued.
