Global Parts 1812278 Exhaust Gas Temperature (EGT) Sensor

Exhaust Gas Temperature Sensor for Ram

Global Parts 1812278 is an exhaust gas temperature (EGT) sensor built for direct replacement service on select Ram trucks. It sends accurate temperature data to the ECM, helping the engine management system maintain proper control of fuel, exhaust, timing, and cooling functions.

• Exhaust Gas Temperature (EGT) sensor for emission control applications
• Direct replacement design that meets OE specifications
• Blade terminal type with 2-wire construction
• Oval female connector with 2 terminals
• Built for accurate ECM temperature input
• Compatible with Ram 1500 and Ram 1500 Classic before catalyst locations

Detailed Product Information

This Global Parts EGT sensor, part number 1812278, is engineered for vehicles that rely on precise exhaust temperature feedback to manage emissions and engine operation. The blade terminals, oval female connector, and 2-wire layout support a straightforward OE-style electrical connection. For Ram 1500 and Ram 1500 Classic applications, the sensor is positioned before the catalyst, where accurate exhaust gas temperature readings are critical to system performance.

Global Parts 1812278 cross-references Dorman OE Solutions 904-789 for the same application. It also aligns with other listed interchange numbers used in the same fitment range.

Vehicle Fitment

• Fits 2019 Ram 1500 Classic, before catalyst.
• Fits 2014-2018 Ram 1500, before catalyst.

What This Sensor Helps Address

• Faulty exhaust gas temperature readings
• Check engine light concerns related to EGT sensor performance
• Incorrect ECM input affecting fuel or timing control
• Emission system monitoring issues
• Temperature signal problems at the before-catalyst location

Installation Notes and Tips

Confirm connector shape, terminal count, and sensor location before installation. This part uses a female oval connector with blade terminals and is specified for before-catalyst placement on the listed Ram applications. Verify the original sensor position and electrical connection against the vehicle before replacement.
