Global Parts 1814753 Exhaust Gas Temperature (EGT) Sensor - Before SCR Catalyst

Exhaust Gas Temperature Sensor for Cadillac Escalade

Global Parts 1814753 is an exhaust gas temperature (EGT) sensor built to send accurate temperature data to the ECM. It is a direct replacement sensor for emission control systems and is engineered to meet OE specifications for the 2021 Cadillac Escalade and 2021 Cadillac Escalade ESV before the SCR catalyst.

Key Features

• Exhaust gas temperature (EGT) sensor for emission control applications
• Direct replacement design for OE-style fit and function
• Supports accurate ECM input for fuel, exhaust, timing, and cooling system control
• Oval female connector with 2 terminals
• Blade terminal type with 1-wire construction
• Fits 2021 Cadillac Escalade, before SCR catalyst
• Fits 2021 Cadillac Escalade ESV, before SCR catalyst
• Part number 1814753 for easy cross-reference

Detailed Description

Global Parts 1814753 is an emission control sensor used to monitor exhaust temperature and relay that information to the engine control module. Accurate EGT sensor input helps the ECM manage critical engine functions, including fuel delivery, exhaust aftertreatment, ignition timing, and cooling strategy. This sensor is a direct replacement for OE part number 55491112 and cross-references ES113348 for the same application. It is a strong match for 2021 Cadillac Escalade and 2021 Cadillac Escalade ESV models positioned before the SCR catalyst.

Common Issues This Sensor May Address

• Check engine light related to exhaust temperature sensor performance
• Incorrect exhaust temperature readings reported to the ECM
• Emission control faults tied to the SCR catalyst monitoring circuit
• Driveability concerns caused by inaccurate sensor input
• Fault codes affecting fuel, timing, or cooling system decisions

Installation Notes and Tips

Confirm the connector shape, terminal count, and sensor position before installation. This part uses an oval female connector, 2 terminals, a blade terminal type, and 1-wire construction. Verify the vehicle is a 2021 Cadillac Escalade or 2021 Cadillac Escalade ESV and that the sensor location is before the SCR catalyst. Compare the original OE number 55491112 to confirm application match.

Quality Assurance

Global Parts engine management sensors are built to meet OE specifications and provide accurate information to the ECM. This helps maintain proper system communication in emission control applications and supports reliable replacement of the original sensor.
