ISX & X15 Applications

Prevent false regen failures and costly engine derates with genuine OEM Cummins DPF Differential Pressure Sensors.

The DPF differential pressure sensor monitors exhaust pressure before and after the Diesel Particulate Filter (DPF). This data allows the ECM to determine soot load levels and properly control regeneration cycles. When this sensor fails, it can lead to inaccurate soot readings, failed regens, and engine torque derate conditions.

At Pro Truck Direct, we supply commercial-grade Cummins differential pressure sensors engineered specifically for:

• Cummins ISX

• Cummins X15

• ISB and ISL applications (verify Engine Serial Number)

Common symptoms of a failing DPF differential pressure sensor include:

• Frequent or failed regeneration cycles

• Excessive soot load warnings

• DPF efficiency fault codes

• Inaccurate soot level readings

• Engine derate

Replacing a faulty differential pressure sensor early can prevent unnecessary DPF cleaning or replacement, saving significant downtime and repair costs.

Our sensors are designed for heavy-duty commercial applications and built to withstand high heat, vibration, and demanding operating environments.

Whether you manage a fleet, operate as an owner-operator, or run a diesel repair shop, Pro Truck Direct provides reliable emissions components to keep your truck running at full performance.
