http://LK21-5L216-BA Particulate Matter Sensor

WJIECO LK21-5L216-BA particulate matter sensor is an OEM replacement PM sensor designed for diesel vehicle DPF exhaust aftertreatment systems. It monitors exhaust particulate concentration and transmits real-time data to ECU to support DPF regeneration, helping eliminate check engine lights and emission-related fault codes. Rigorous factory testing guarantees reliable performance in harsh exhaust environments.

LK21-5L216-BA Particulate Matter Sensor The WJIECO LK21-5L216-BA particulate matter sensor is a direct aftermarket replacement part matching OE number LK21-5L216-BA. This PM sensor serves as a core component of diesel DPF (Diesel Particulate Filter) exhaust aftertreatment systems. It detects soot and particulate matter concentration within vehicle exhaust gas and sends real-time measurement signals to the engine control unit. With accurate sensor feedback, the ECU controls DPF regeneration cycles properly to meet emission standards and avoid dashboard warning faults.

Our WJIECO LK21-5L216-BA particulate matter sensor is manufactured strictly according to original OE specifications. Physical dimensions, connector pin layout, internal sensing circuit and probe structure fully match the original LK21-5L216-BA unit. Plug-and-play installation without cutting, drilling or extra modification, saving time for repair shops and DIY installers. It is the ideal replacement when your factory sensor fails and triggers DPF fault codes, check engine lights, failed emission inspection or inaccurate soot reading errors.

Key Features

1. Exact OE part number LK21-5L216-BA for quick part lookup and vehicle cross-check.
2. High-sensitivity detection chip, delivering steady signal output under high temperature, vibration and corrosive exhaust conditions.
3. Heavy-duty high-temperature resistant housing, anti-corrosion and anti-aging for long-term use.
4. 100% full function testing before shipment. Every WJIECO particulate sensor goes through signal calibration, temperature cycling and aging inspection for stable quality.
5. Affordable aftermarket alternative, performance comparable to OEM parts with lower cost.
6. Pre-calibrated sensor module, ready for installation right out of package.

Vehicle Application

This LK21-5L216-BA particulate matter sensor fits diesel vehicles equipped with matching DPF exhaust systems. Please carefully verify your original OE number LK21-5L216-BA, sensor appearance, connector shape and pin definition before ordering. Even vehicles from the same series may adopt different PM sensors for different chassis configurations. Cross-referencing the OE number is the best method to prevent mismatched parts and return troubles.

Installation & Maintenance Notes

Professional mechanic installation is strongly recommended for this particulate matter sensor.

1. Disconnect the vehicle battery before removing the old sensor to avoid ECU short-circuit damage.
2. Check wiring harness and connector pins for corrosion or wear while replacing the sensor.
3. After installation, clear DPF-related fault codes with professional diagnostic scanner.
4. Complete forced DPF regeneration test to confirm the new LK21-5L216-BA PM sensor reads soot values normally.
5. Never clean the sensor probe with abrasive chemicals; contamination will permanently reduce detection precision.
