DPF Monitoring Components

Maintain proper DPF performance and prevent costly engine derates with genuine OEM and ReCon Cummins Particulate Matter (PM) sensors.

PM sensors are a critical component of the aftertreatment system. They monitor soot levels in the exhaust stream and communicate directly with the ECM to ensure proper DPF regeneration cycles. When a particulate sensor fails, it can disrupt regeneration, increase soot accumulation, and lead to emissions-related fault codes and power reduction.

At Pro Truck Direct, we supply high-quality Cummins PM sensors engineered specifically for:

• Cummins ISX

• Cummins X15

• ISB and ISL applications (verify Engine Serial Number)

Common symptoms of a failing particulate matter sensor include:

• Failed or incomplete DPF regenerations

• DPF efficiency fault codes

• Excessive soot buildup

• Increased exhaust backpressure

• Engine torque derate

Replacing a faulty PM sensor promptly can prevent expensive DPF damage and extended downtime.

Many of our Cummins ReCon particulate sensors include a refundable core charge, clearly noted in each product listing.

Whether you manage a fleet, operate as an owner-operator, or run a diesel repair facility, our PM sensors are designed to restore proper DPF monitoring and keep your truck compliant and on the road.
