Product Description | Particulate Matter Sensor (PM Sensor)

The Particulate Matter Sensor WG1034121035 is an OEM-standard exhaust emission sensor designed for SINOTRUK heavy-duty trucks. Also cross-referenced with 0281007204 / 0281007082, this PM sensor is installed in the exhaust after-treatment system, where it continuously monitors the particulate matter (soot) concentration in exhaust gases.

By providing real-time feedback to the engine ECU, the sensor helps optimize DPF regeneration, control emissions, and ensure compliance with emission regulations. It plays a critical role in maintaining engine efficiency, emission stability, and system protection.

Manufactured with high-precision sensing elements, heat-resistant materials, and reliable electrical connectors, the PM sensor offers accurate measurement, fast response, and long service life. It is engineered to operate reliably under high exhaust temperatures, vibration, and harsh working conditions, making it suitable for long-haul and heavy-duty truck applications.

Produced strictly according to OEM technical specifications, the sensor ensures accurate fitment, stable signal output, and plug-and-play installation.
