WJIECO JS7A-5L239-AA PM Sensor for DPF Ford Mondeo MK4 MK5 diesel. Cross reference Bosch OEM 0281007158. Plug-and-play, fixes DPF regeneration & particulate fault codes.

JS7A-5L239-AA PM Sensor Overview

The JS7A-5L239-AA PM Sensor (OE# JS7A-5L239-AA, Bosch OEM#0281007158) is OEM-grade DPF Particulate Matter Sensor manufactured by WJIECO for Ford Mondeo MK4 MK5 diesel vehicles. Also known as soot sensor, this critical exhaust aftertreatment component mounts downstream of the Diesel Particulate Filter (DPF). It detects fine particulate soot concentration in exhaust gas exiting DPF and transmits real-time particulate readings to the ECU. The ECU uses this signal to trigger, regulate and monitor automatic DPF regeneration, which is mandatory to meet modern diesel vehicle emissions standards.

This JS7A-5L239-AA PM Sensor serves as a direct factory replacement part for compatible Ford Mondeo MK4 MK5 diesel models.

If your Ford Mondeo diesel sedan triggers persistent check engine light, DPF regeneration failure, forced limp mode, soot overload warning or particulate-related diagnostic trouble codes, your factory PM Sensor may suffer from probe contamination, carbon soot fouling, signal drift or internal circuit aging damage. Replacing the faulty original sensor with this direct-fit JS7A-5L239-AA PM Sensor is a cost-effective solution to restore your diesel exhaust aftertreatment system.

H2: OEM-Grade Construction and Strict Factory Testing

Our replacement JS7A-5L239-AA PM Sensor is equipped with precision soot detection probe and reinforced anti-vibration internal circuit module. It is engineered to withstand extreme exhaust temperature, thermal cycling and heavy vibration during highway cruising and heavy-load driving conditions. The outer protective housing, wiring harness and multi-pin electrical plug connector fully match OE and Bosch factory specifications, preventing wire cracking, water ingress and intermittent signal dropouts.

Every finished JS7A-5L239-AA PM Sensor unit undergoes high-temperature aging test, soot signal calibration and waterproof sealing inspection before shipment. This strict quality check eliminates common defects found on cheap generic sensors, including unstable particulate readings, slow signal response and early premature failure under high soot loads.

As a core component of modern diesel exhaust aftertreatment system, this JS7A-5L239-AA PM Sensor allows ECU to evaluate DPF filtration efficiency and manage regeneration cycles. A defective PM Sensor will block DPF regeneration, trigger limp mode, cause DPF clogging and illuminate the check engine light. Common DTC fault codes include P2452, P2453, P2454, P2463.

H2: Core Benefits of Upgrading to the JS7A-5L239-AA PM Sensor

Replacing your malfunctioning factory DPF soot detector with our pre-calibrated WJIECO JS7A-5L239-AA PM Sensor brings obvious reliability upgrades and protects your expensive diesel particulate filter. Unlike low-cost aftermarket sensors that frequently trigger fault codes due to poor calibration, our sensor delivers stable and accurate soot concentration data to the vehicle ECU.

Reliable sensor measurements help the engine computer run normal DPF regeneration, avoid unexpected limp mode, reduce DPF soot buildup and keep your Ford Mondeo compliant with emissions regulations. After installation, you can clear particulate sensor related trouble codes and restore full engine power.

H2: Plug-and-Play Installation, No Dealer Programming Required

A key advantage of this JS7A-5L239-AA PM Sensor is true plug-and-play design built for compatible Ford Mondeo MK4 MK5 diesel models. This replacement part requires no ECU reprogramming, manual calibration, wire cutting or complex mechanical modifications.

Installation works great for both professional repair garages and DIY vehicle owners. Simply remove the old PM Sensor from exhaust pipe after DPF, apply anti-seize compound on threads, align and screw in the new sensor, reconnect factory wiring plug, then clear stored fault codes using an OBD diagnostic scanner. After a short normal driving cycle, the DPF aftertreatment system will return to stable operation without recurring warning alerts.

Every WJIECO JS7A-5L239-AA PM Sensor passes complete functional testing before leaving our factory. If you need durable, high-precision and affordable OEM replacement DPF PM Sensor matching OE JS7A-5L239-AA and Bosch OEM 0281007158 for your Ford Mondeo MK4 MK5, our JS7A-5L239-AA PM Sensor is the ideal choice to restore your diesel exhaust aftertreatment system.
