MB3A-5L239-AB Particulate Matter Sensor
The WJIECO MB3A-5L239-AB particulate matter sensor is a direct OE replacement PM sensor built for diesel vehicle exhaust aftertreatment systems. This sensor is a core component of the DPF diesel particulate filter system, responsible for measuring the concentration of particulate matter in exhaust gas and sending real-time signal data to the ECU engine control unit. Accurate signal feedback enables the vehicle to trigger DPF regeneration properly, maintaining emission compliance and preventing warning lights on your dashboard.

Our WJIECO MB3A-5L239-AB particulate matter sensor is manufactured strictly following OE specifications for perfect fitment. Every dimension, connector pin layout and internal circuit matches the original MB3A-5L239-AB sensor. No cutting, drilling or extra modification is needed during installation, which saves mechanic labor time. This aftermarket PM sensor is an ideal replacement when your original unit fails, triggering common DPF fault codes, check engine lights, failed emission tests or inaccurate soot readings.

### Key Features
1. Matches OE part number MB3A-5L239-AB for fast part lookup and vehicle matching.
2. High precision sensing chip, stable signal output under high temperature, vibration and corrosive exhaust environments.
3. Reinforced high-temperature housing, long service life for heavy-duty driving conditions.
4. 100% full function testing before shipment. Each WJIECO particulate sensor passes signal, temperature and aging testing to guarantee consistent performance.
5. Cost-effective aftermarket alternative, delivering reliable performance close to OEM parts at a much better price point.
6. Pre-calibrated sensor module, ready for installation once you receive the unit.

### Vehicle Application
This MB3A-5L239-AB particulate matter sensor is designed for diesel vehicles equipped with DPF exhaust systems. Always double-check your original OE number MB3A-5L239-AB, sensor physical shape, connector type and pin definition before purchase. Even if two vehicles look similar, different chassis configurations may use different PM sensors. Cross-referencing the OE number is the most reliable way to avoid wrong part orders and return issues.

### Installation & Maintenance Notes
Professional mechanic installation is highly recommended for this particulate matter sensor.
1. Disconnect vehicle battery before removing the old sensor to avoid short circuit damage to ECU.
2. Inspect wiring harness and connector pins for corrosion or damage while replacing the sensor.
3. After finishing installation, clear stored DPF related fault codes with a diagnostic scanner.
4. Complete a forced DPF regeneration cycle to verify the new MB3A-5L239-AB PM sensor reads values correctly.
5. Do not use abrasive cleaners on the sensor probe; contamination will damage sensing accuracy.
