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.
