This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Fault codes related to exhaust temperature sensor performance
• Incorrect exhaust temperature readings
• Emission control system monitoring issues
• Driveability concerns tied to sensor signal loss
• Replacement needs for a damaged or heat-aged EGT sensor

Installation Notes and Tips

Confirm the connector shape, terminal count, thread diameter, and harness length before installation. Because this sensor mounts in the exhaust, inspect the threaded port and surrounding components for heat damage, corrosion, or carbon buildup before fitting the new unit. Verify the vehicle application by year, make, model, and position against the original sensor configuration, especially for Ford, Chevrolet, and Dodge diesel service where EGT sensor layouts can vary.
