Motorcraft DY1269 is an OEM replacement engine coolant temperature sensor assembly for Ford, Lincoln, and Mercury applications. It sends coolant temperature data to the engine control module, helping the vehicle manage fueling, emissions strategy, and overheating protection with a direct-service replacement for failed or inaccurate temperature sensing.

Motorcraft DY1269 Oxygen Sensor Features:

• 2-terminal coolant temperature sensor design provides the signal the engine control module uses to monitor engine temperature.
• Replaces Ford OEM part number 3L8Z-12A648-A and is also referenced against earlier OE numbers 1L2Z-12A648-AA and 3L8Z-12A648-BA.
• Designed as a direct replacement for supported Ford, Lincoln, and Mercury vehicles where DY1269 is specified.
• Underhood-ready construction is intended to handle demanding engine-bay conditions and reduce repeat service.
