Keep an accurate read on engine temperature with the NTK Engine Coolant Temperature Sensor / Engine Oil Temperature Sender (MPN EF0103). It installs as a direct-fit replacement across a broad Ford, Lincoln, Mercury, Mazda, Jaguar and LaForza lineup — including the 1995-2022 Ford Mustang, 1996-2004 Ford F-150, 1994-2008 Ford Ranger and 1994-2001 Ford F-250 — one of 96 listed applications. See the Buyer's Guide tab for the full list.
This sensor uses a temperature-sensitive element whose resistance changes with engine temperature, converting that reading into an electrical signal for the powertrain control module and/or the temperature gauge so the system can track the current operating temperature.
Dual identity: cataloged under both the Engine Coolant Temperature Sensor and Engine Oil Temperature Sender names, so it appears under both.
Function: turns engine temperature into an electrical signal the ECU and gauge can read.
Signs it may need replacing: an erratic, stuck or dead temperature gauge, or a temperature-related trouble code, may point to a failed sensor — diagnose the cause before replacing, since other faults can produce the same symptoms.
Interchange: Manufacturer part number EF0103.
Frequently Asked Questions
What does this NTK sensor do?
It uses a temperature-sensitive element whose resistance varies with engine temperature, sending that signal to the ECU and/or gauge so the system can read the current operating temperature.
Why is it listed under two different names?
It is cataloged as both an Engine Coolant Temperature Sensor and an Engine Oil Temperature Sender, so it appears under both names on our storefront.
Will this sensor fit my vehicle?
It is listed for 96 applications, including the 1995-2022 Ford Mustang, 1996-2004 Ford F-150 and 1994-2008 Ford Ranger. Check the Buyer's Guide tab to confirm your exact year, make and model.
What are the signs this sensor may need replacing?
An erratic, stuck or dead temperature gauge or a temperature-related trouble code can indicate a failed sensor. Diagnose the cause first, since other components can produce the same symptoms.
What is the manufacturer part number?
This is NTK manufacturer part number EF0103.
