WJIECO 12696927 PM Sensor Cross Bosch OEM 0281007711 0281007712 for GMC Sierra Chevrolet Silverado Diesel

12696927 PM Sensor Overview

The 12696927 PM Sensor (GM OE# 12696927, Bosch OEM# 0281007711, 0281007712) is an OEM-grade DPF PM Sensor engineered by WJIECO for heavy-duty diesel pickup trucks. Also known as soot sensor, this critical aftertreatment component mounts downstream of the Diesel Particulate Filter (DPF). It detects the concentration of fine particulate soot in exhaust gas leaving the DPF and transmits real-time particulate readings to the ECU. The ECU uses this signal to trigger, regulate and monitor DPF automatic regeneration, which is mandatory for modern diesel emissions compliance.

This PM Sensor is designed as a direct factory replacement for these applications: GMC Sierra, Chevrolet Silverado.

If your GM diesel pickup triggers a persistent check engine light, DPF regeneration failure, forced limp mode, soot overload warning or particulate related diagnostic trouble codes, your factory PM Sensor is likely suffering from probe contamination, carbon soot fouling, signal drift or internal circuit aging damage. Replacing the defective original sensor with this direct-fit 12696927 replacement part is a cost-effective solution to restore your diesel aftertreatment system.

OEM-Grade Construction and Strict Factory Testing

Our replacement 12696927 PM Sensor features a precision soot detection probe and reinforced anti-vibration internal circuit module. It is engineered to withstand extreme exhaust temperature, thermal cycling and strong vibration during highway cruising and heavy hauling conditions. The outer protective housing, wiring harness and multi-pin electrical plug connector are fully dimension-matched to GM OEM and Bosch factory specifications, preventing wire cracking, water ingress and intermittent signal dropouts.

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

Exact Vehicle Compatibility & Interchange OE Numbers

This DPF downstream PM Sensor is a direct replacement for the below diesel pickup models. Interchange Part Numbers:

• GM OE: 12696927
• Bosch OEM: 0281007711, 0281007712

Fitment List:

• GMC Sierra
• Chevrolet Silverado

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

Core Benefits of Upgrading to the 12696927 PM Sensor

Replacing your malfunctioning factory DPF soot detector with our pre-calibrated WJIECO 12696927 PM Sensor delivers noticeable reliability improvements and protects expensive diesel particulate filters. Unlike low-cost aftermarket sensors that repeatedly trigger fault codes due to poor calibration, our unit provides steady, accurate soot concentration data for the vehicle ECU.

Reliable sensor measurements enable the engine computer to execute normal DPF regeneration, avoid unplanned limp mode, reduce DPF soot buildup and keep your diesel vehicle compliant with emissions regulations. After installation, you can clear particulate sensor related trouble codes and restore full engine power.

Plug-and-Play Installation, No Dealer Programming Required

A key advantage of this 12696927 PM Sensor is its true plug-and-play design built for compatible GM diesel pickup 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 old PM Sensor from the exhaust pipe after DPF, apply anti-seize compound on threads, align and screw in 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 DPF aftertreatment system will return to stable operation without recurring warning alerts.

Every WJIECO PM Sensor passes complete functional testing before leaving our factory. If you need a durable, high-precision and affordable OEM replacement DPF PM Sensor matching GM OE 12696927 and Bosch OEM 0281007711 / 0281007712 for your GMC Sierra or Chevrolet Silverado, our 12696927 PM Sensor is the ideal choice to restore your diesel exhaust aftertreatment system.
