HC34-5L239-DA PM Sensor WJIECO HC34-5L239-DA DPF Particulate Matter PM Sensor for Ford F250 F350 F450 F550 Super Duty 6.7L Powerstroke Diesel

HC34-5L239-DA PM Sensor Overview

The HC34-5L239-DA PM sensor is an OEM-grade diesel particulate matter exhaust sensor engineered by WJIECO for Ford Super Duty heavy-duty trucks equipped with the 6.7L Powerstroke diesel engine. Also referred to as a soot sensor or DPF particulate detector, this critical exhaust aftertreatment component measures real-time soot concentration inside the exhaust piping and transmits accurate signal data to the vehicle ECU to regulate active DPF regeneration cycles.

If your Ford F250/F350/F450/F550 Super Duty 6.7L Powerstroke displays a persistent check engine light, reduced engine power, DPF warning messages, repeated failed regeneration attempts or DPF related trouble codes, your factory particulate sensor has likely suffered signal drift, heating element burnout or physical damage. Replacing the faulty stock sensor with this direct-fit HC34-5L239-DA replacement part is the most cost-effective way to restore full functionality to your diesel particulate filter system.

OEM-Grade Construction and Strict Factory Testing

Our replacement HC34-5L239-DA PM sensor adopts a high-temperature resistant ceramic detection probe and reinforced anti-vibration internal circuit board designed to withstand extreme exhaust heat and continuous road vibration during heavy towing and long highway cruising. The outer housing, wiring harness and electrical plug connector are fully dimension-matched to original OEM standards, effectively preventing wire cracking, water ingress and intermittent signal failure.

Every finished unit undergoes high-temperature aging testing, signal calibration and waterproof sealing inspection before shipment. This process eliminates common defects found in cheap generic sensors, such as unstable soot readings, delayed signal response and premature component failure.

Exact Vehicle Compatibility

This exhaust particulate matter sensor is manufactured to perfectly fit Ford F-250, F-350, F-450, F-550 Super Duty 6.7L Powerstroke diesel models. It directly cross-replaces OEM part numbers HC34-5L239-DB and HC3Z-5L239-D. As a core control component of the DPF system, the soot sensor directly determines the ECU’s judgment of exhaust particulate load and triggers regeneration at the correct interval. A malfunctioning detector will trigger constant dashboard warning lights, severe DPF clogging and failure to pass official emissions inspections.

Core Benefits of Upgrading to the HC34-5L239-DA PM Sensor

Replacing your faulty factory soot detector with our pre-calibrated WJIECO HC34-5L239-DA PM sensor delivers measurable driving performance upgrades and reduces heavy truck maintenance costs. Unlike budget aftermarket sensors that trigger recurring trouble codes due to inaccurate factory calibration, our unit outputs consistent, precise particulate data for the vehicle ECU.

Accurate sensor readings allow the powertrain computer to initiate DPF regeneration at the optimal timing, reduce excessive soot buildup inside the diesel particulate filter and avoid costly full DPF replacement caused by irreversible blockage. After installation, you will notice restored throttle responsiveness, stabilized fuel mileage and elimination of DPF-related diagnostic fault codes.

Plug-and-Play Installation, No Dealer Programming Required

A major advantage of this HC34-5L239-DA PM sensor is its true plug-and-play design customized for Ford Super Duty 6.7L Powerstroke. This replacement part requires no ECU reprogramming, manual calibration, wire cutting or complex mechanical modifications.

The installation workflow is friendly for both professional diesel repair shops and DIY truck owners. Simply remove the damaged old sensor from the exhaust pipe, align the mounting holes to secure the new unit, reconnect the factory wiring plug, then clear historical fault codes using an OBD diagnostic scanner. After a short normal driving cycle, the truck’s DPF emission system will return to fully stable operation without repeated fault alerts.

Every WJIECO sensor passes complete functional verification before shipment. If you are searching for a durable, high-precision and budget-friendly OEM replacement soot sensor for your Ford Super Duty 6.7L Powerstroke truck, our HC34-5L239-DA PM sensor is the ideal choice to restore your vehicle’s emission system health.
