Detailed Description

Walker Products 273-10335 is an exhaust gas temperature sensor used in diesel exhaust aftertreatment systems to monitor exhaust heat at specific points in the system. This sensor is listed for multiple Ram 2500 and Ram 3500 configurations, including T4 before DOC, T5 after DOC, T6 after DPF, T7 before SCR, and T8 after SCR applications. If you are servicing a 2007-2010 Dodge Ram 2500 or Dodge Ram 3500, or a 2011-2012 Ram 2500 or Ram 3500 cab chassis model, this part number is a direct fitment reference to verify against your vehicle’s exhaust system code.

Walker Products has supplied automotive engine management components since 1946 and manufactures to meet or exceed OEM standards and specifications. The Walker Products line includes sensors and other engine management parts, with engineering and product support focused on application accuracy. This part cross-references Standard Ignition ETS67 for the same application.

Common Issues This Sensor May Address

• Fault codes related to exhaust gas temperature sensor performance
• Incorrect exhaust temperature readings in diesel emission systems
• Check engine light concerns tied to EGT sensor failure
• Aftertreatment system monitoring errors on DOC, DPF, or SCR-equipped trucks
• Service replacement for worn or damaged exhaust sensor wiring or connector ends

Installation Notes and Tips

Verify the exhaust system code on the vehicle before ordering, since fitment varies by T4, T5, T6, T7, and T8 configurations. Confirm connector shape, thread diameter, and mounting location against the original sensor before installation. For best results, inspect the exhaust bung and wiring routing for heat damage, corrosion, or contamination before replacing the sensor.
