ISX & X15 Aftertreatment Components

Maintain proper SCR performance and prevent emissions-related engine derates with genuine OEM Cummins SCR temperature sensors.

SCR (Selective Catalytic Reduction) temperature sensors monitor exhaust gas temperatures throughout the aftertreatment system. These readings are critical for proper DEF dosing, SCR efficiency, and regeneration strategy. When a temperature sensor fails, it can cause inaccurate exhaust readings, fault codes, and reduced engine performance.

At Pro Truck Direct, we supply OEM Cummins SCR temperature sensors engineered specifically for:

• Cummins ISX

• Cummins X15

• ISB and ISL configurations (verify Engine Serial Number)

Common symptoms of a failing SCR temperature sensor include:

• SCR efficiency fault codes

• DEF dosing errors

• Failed or improper regeneration cycles

• Check engine light

• Engine torque derate

Accurate temperature monitoring is essential to keeping your aftertreatment system compliant and functioning properly. Replacing a faulty sensor promptly can prevent unnecessary downtime and additional emissions component damage.

Whether you manage a fleet, operate as an owner-operator, or run a diesel repair facility, our SCR temperature sensors are built to restore dependable aftertreatment performance under demanding commercial conditions.
