The HC34-5L239-DA PM Sensor is a critical diesel exhaust aftertreatment component for US-market Ford Super Duty 6.7L Powerstroke trucks. If you are searching for a durable, direct-fit replacement HC34-5L239-DA PM Sensor, WJIECO delivers aftermarket quality that matches top-selling units listed on Amazon US auto parts market.
Commonly known as a DPF soot sensor, the HC34-5L239-DA PM Sensor mounts downstream of the diesel particulate filter. Its core job is to continuously detect soot particle levels inside exhaust gas and send real-time readings to the truck ECU. Without a working HC34-5L239-DA PM Sensor, your Ford truck cannot accurately manage DPF regeneration, monitor filter health or maintain EPA emissions compliance. Many US diesel mechanics and fleet owners turn to replacement HC34-5L239-DA PM Sensor when their dash lights trigger and DPF related trouble codes appear.

Important note: Always verify your VIN before purchase to confirm fitment. This HC34-5L239-DA PM Sensor works exclusively for 6.7L Powerstroke diesel engines and will not fit gasoline Ford trucks.
Common Symptoms When HC34-5L239-DA PM Sensor Fails
A faulty HC34-5L239-DA PM Sensor creates a range of noticeable driveability and emissions issues. These are the most frequent complaints US truck owners report, and the top reasons they shop for replacement DPF sensors online:
- Check Engine Light (CEL) stays illuminated on dashboard
- DPF warning light activates
- DPF regeneration cycle stuck or forced regeneration fails
- Reduced engine power and vehicle derate condition
- Common diagnostic trouble codes: P2463, P244B, P2452, P2453
- Incorrect soot readings and false DPF full alerts
- Failure during state emissions inspection
When your HC34-5L239-DA PM Sensor stops working properly, the ECU cannot measure exhaust soot accurately. Even if your DPF filter remains in good condition, the truck computer will limit engine power to protect emissions systems. This creates costly downtime for contractors, farm operators and daily truck drivers. Swapping in the WJIECO HC34-5L239-DA PM Sensor restores proper DPF operation and clears stored fault codes.

Step-by-Step Installation Guide for HC34-5L239-DA PM Sensor
Installing the WJIECO HC34-5L239-DA PM Sensor is manageable for experienced DIY truck owners and professional repair technicians.
Step 1: Prepare for Installation
Park your Ford Super Duty on level ground and shut the engine off. Allow the full exhaust system to cool completely; hot exhaust components can cause serious burns. Gather basic hand tools and an OBD2 scanner to clear fault codes after installing the new HC34-5L239-DA PM Sensor.
Step 2: Locate and Disconnect the Old Sensor
The HC34-5L239-DA PM Sensor installs on exhaust pipe after the DPF filter. First disconnect the electrical harness plug from the sensor.
Step 3: Remove Old HC34-5L239-DA PM Sensor
Unscrew the old sensor from exhaust threads. Clean the threaded mounting seat thoroughly to remove carbon deposits and rust before fitting the new HC34-5L239-DA PM Sensor.
Step 4: Mount WJIECO HC34-5L239-DA PM Sensor
Thread your new WJIECO HC34-5L239-DA PM Sensor into position and torque to manufacturer specifications. Securely reconnect the wiring harness connector. The included sealing gasket ensures no exhaust leakage at the mounting point.
Step 5: Reset Codes & Complete Drive Cycle Test
Start the engine, use your OBD scanner to erase stored DPF fault codes. Run the truck through a proper drive cycle to verify live signal data from the HC34-5L239-DA PM Sensor and confirm DPF regeneration works normally. Double-check that the check engine light remains off.
Professional Installation Tip: Never touch the sensing probe of your new HC34-5L239-DA PM Sensor with bare hands. Skin oils and grease will contaminate the probe and lead to premature sensor failure.
