WJIECO SH9P-18641B PM Sensor Diesel Exhaust Particulate Matter Sensor Fits For Mazda CX-5 KE/KF、Mazda6 GJ 2.2L Skyactiv-D Diesel Car 0281007918 0281007919 SH9P18641B

SH9P-18641B PM Sensor Overview

The SH9P-18641B PM sensor is an OEM-grade diesel particulate matter exhaust sensor engineered by WJIECO for Mazda CX-5 KE/KF and Mazda6 GJ vehicles fitted with the 2.2L Skyactiv-D diesel engine. Also known as a soot sensor or DPF particulate detector, this vital exhaust aftertreatment component measures real-time soot concentration within the exhaust pipe. It transmits precise signal readings to the vehicle ECU to manage and trigger active DPF regeneration cycles automatically.

If your Mazda CX-5 or Mazda6 2.2L Skyactiv-D diesel triggers a persistent check engine light, reduced engine power, DPF dashboard warnings, failed regeneration cycles or DPF-related diagnostic trouble codes, your factory particulate sensor is likely suffering from signal drift, burnt heating element or physical damage. Replacing the defective original sensor with this direct-fit SH9P-18641B replacement part is a cost-effective solution to fully restore your diesel particulate filter system.

OEM-Grade Construction and Strict Factory Testing

Our replacement SH9P-18641B PM sensor features a high-temperature resistant ceramic detection probe and reinforced anti-vibration internal circuit board. It is engineered to withstand extreme exhaust heat and continuous vibration from daily highway driving. The outer housing, wiring harness and electrical plug connector are fully dimension-matched to OEM factory specifications, preventing wire cracking, water ingress and intermittent signal failures.

Every finished sensor unit goes through high-temperature aging testing, signal calibration and waterproof sealing inspection before shipment. This quality check eliminates common flaws found in cheap generic sensors, such as unstable soot readings, delayed signal response and early premature failure.

Exact Vehicle Compatibility

This exhaust particulate matter sensor is made to perfectly fit Mazda CX-5 KE/KF and Mazda6 GJ with Skyactiv-D 2.2L diesel engines. It directly cross-replaces OEM part numbers 0281007918 and 0281007919. As a core control component of the DPF system, the soot sensor allows the ECU to calculate exhaust particulate load and activate regeneration at the proper time. A faulty detector will cause constant warning lights, severe DPF clogging and failure to complete official emissions testing.

Core Benefits of Upgrading to the SH9P-18641B PM Sensor

Replacing your malfunctioning factory soot detector with our pre-calibrated WJIECO SH9P-18641B PM sensor delivers noticeable performance improvements and cuts long-term maintenance expenses. Unlike low-cost aftermarket sensors that repeatedly trigger fault codes due to poor calibration, our unit provides steady, accurate particulate data for the vehicle ECU.

Reliable sensor measurements enable the powertrain computer to run DPF regeneration at optimal intervals, reduce soot accumulation inside the diesel particulate filter, and prevent expensive full DPF replacement caused by irreversible blockage. After installation, you will recover throttle responsiveness, stabilize fuel consumption and clear DPF-related trouble codes.

Plug-and-Play Installation, No Dealer Programming Required

A key advantage of this SH9P-18641B PM sensor is its true plug-and-play design built for Mazda 2.2L Skyactiv-D diesel models. This replacement part requires no ECU reprogramming, manual calibration, wire cutting or complicated mechanical modifications.

Installation works well for both professional repair garages and DIY vehicle owners. Simply remove the damaged old sensor from the exhaust pipe, align mounting holes and secure the new sensor, reconnect the factory wiring plug, then clear stored fault codes using an OBD diagnostic scanner. After a short normal driving cycle, the Mazda DPF emission system will return to stable operation without recurring warning alerts.

Every WJIECO sensor passes complete functional testing before leaving our factory. If you need a durable, high-precision and affordable OEM replacement soot sensor for your Mazda CX-5 / Mazda6 2.2 Skyactiv-D diesel car, our SH9P-18641B PM sensor is the ideal choice to restore your exhaust emission system.
