Meta Description: Shop premium HC3Z-5L239-D particulate matter sensor for Ford F-250, F-350 Super Duty 6.7L diesel. Fix DPF errors, limp mode & failed regens with OEM-grade WJIECO replacement sensor.
H1: HC3Z-5L239-D Diesel Exhaust Particulate Sensor – OEM Replacement for Ford F-250 & F-350 6.7L Diesel
If your Ford Super Duty 6.7L diesel truck throws DPF fault codes, enters limp mode, or fails diesel particulate filter regeneration cycles, a defective HC3Z-5L239-D diesel exhaust particulate sensor (PM sensor) is one of the most frequent culprits. This critical aftertreatment sensor monitors soot output downstream of the DPF, communicates real-time particulate data to the truck’s ECU, and keeps your pickup compliant with EPA diesel emissions regulations across the United States.
At WJIECO, we manufacture direct-fit HC3Z-5L239-D particulate sensors engineered to match OEM dimensions, wiring connectors, and performance for 2017–2022 Ford F-250 and F-350 Super Duty 6.7L diesel models. This guide breaks down everything truck owners, fleet mechanics, and DIY technicians need to know about the HC3Z-5L239-D PM sensor: fitment details, failure symptoms, diagnostic trouble codes, installation steps, and why our WJIECO aftermarket sensor beats costly dealership OEM replacements.
H2: What Is the HC3Z-5L239-D Diesel Exhaust Particulate Sensor & How It Works
H3: Core Function of the Particulate Matter (PM) Sensor
The HC3Z-5L239-D is a factory-spec particulate matter sensor mounted directly after the diesel particulate filter (DPF) on your Ford 6.7L exhaust system. It features internal heating elements and conductive electrode probes that measure soot leakage through the DPF canister:
- Soot particles create electrical conductivity across the sensor electrodes;
- The sensor module sends voltage signals to the engine control module (ECM);
- The ECM triggers active DPF regeneration if soot levels exceed factory thresholds;
- A built-in 600°C+ heating element self-cleans soot buildup on the sensor probe during normal operation.
Without a working HC3Z-5L239-D sensor, your truck cannot properly manage DPF regeneration, leading to costly exhaust system damage, failed state emissions testing, and mandatory power derating.

H2: Top Warning Signs of a Failed HC3Z-5L239-D Particulate Sensor
A faulty HC3Z-5L239-D sensor rarely fails completely overnight. Watch for these progressive symptoms to avoid being stranded or paying for expensive DPF repairs:
H3: Dashboard Warning Lights & Fault Codes
- Solid Check Engine Light (MIL) illumination
- DPF Exhaust System Warning Light or Regeneration Required alert
- Common OBD2 Fault Codes linked to HC3Z-5L239-D failure: P2463, P2452, P2453, P2454, P2269
H3: Performance & Operational Issues
- Limp Mode / Reduced Engine Power: The ECM limits horsepower to protect the clogged DPF from cracking or melting under excess exhaust pressure
- Failed or Constant DPF Regeneration: Truck cycles active regen nonstop (wasting diesel fuel) or refuses to initiate regen entirely
- Sharp Drop in Fuel Mileage: Unnecessary regeneration cycles can cut highway MPG by 5–10% for heavy-duty pickups
- Black Exhaust Smoke During Acceleration: Unfiltered soot bypasses the DPF due to bad sensor readings
- Hard Cold Starts & Rough Idle: Misfueling adjustments from incorrect exhaust particulate data disrupt idle stability
H3: Long-Term Risks of Delaying Sensor Replacement
Running your truck with a bad HC3Z-5L239-D sensor leads to catastrophic DPF clogging, exhaust backpressure damage to turbochargers, and automatic emissions inspection failure in California, Texas, Illinois, and all states with diesel smog checks. Replacing the $100–$200 PM sensor prevents a $2,000+ DPF replacement bill at a Ford dealership.
H2: Why Choose WJIECO HC3Z-5L239-D Diesel Exhaust Particulate Sensor?

H2: DIY Installation Steps for HC3Z-5L239-D PM Sensor (Ford 6.7L Super Duty)
Home mechanics with basic hand tools can replace the HC3Z-5L239-D sensor in 30–45 minutes with a floor jack and jack stands:
- Cool the truck exhaust completely (minimum 2 hours after driving to avoid burns)
- Raise the rear of the truck to access the exhaust pipe directly behind the DPF canister
- Unplug the OEM wiring connector from the particulate sensor module
- Use a socket wrench to remove the two mounting bolts securing the old HC3Z-5L239-D sensor to the exhaust pipe
- Clean the exhaust mounting surface of soot and rust before installing the new WJIECO sensor
- Torque mounting bolts to factory specification, reconnect the wiring harness
- Clear stored DPF fault codes with an OBD2 scanner
- Take a 15–20 mile highway drive to trigger a passive DPF regeneration and verify warning lights stay off
H3: Pro Installation Tip
Coat the sensor mounting threads with anti-seize compound to prevent rust seizure for future service, critical for northern US states with road salt exposure.
H2: Frequently Asked Questions About HC3Z-5L239-D Particulate Sensors
H3: Can I clean a faulty HC3Z-5L239-D sensor instead of replacing it?
No. The internal electrode and heating element degrade permanently with soot saturation and thermal fatigue. Surface cleaning cannot restore accurate sensor readings, and temporary cleaning will result in returning check engine lights within 500–1,000 miles. Direct replacement is the only permanent fix.
H3: Will a replacement HC3Z-5L239-D sensor pass emissions testing?
Yes. WJIECO HC3Z-5L239-D sensors are manufactured to OEM emissions calibration specs and are legal for all US state diesel emissions inspections. Deleting or bypassing the PM sensor will cause immediate inspection failure.
H3: How long does a WJIECO HC3Z-5L239-D particulate sensor last?
Under regular highway driving with ULSD diesel fuel, our sensors deliver 100,000–150,000 miles of service life, matching OEM service life expectationsAlibaba.co…. Short city trips accelerate sensor wear due to incomplete DPF regeneration cycles.
H3: Does this sensor work for cab-and-chassis Ford F-350 models?
Yes, the HC3Z-5L239-D fitment includes cab-chassis 6.7L Super Duty work trucks used for fleets, plow trucks, and utility service vehicles.
