Bosch 0281007877 Diesel Particulate Matter Sensor
Best for: Buyers looking for an OE-oriented sensor with pre-calibrated electronics. Bosch lists low-soot detection down to 1 mg/m³, fast response, and a service life of up to 155,000 miles. Its stainless steel sensor housing and molded sensor control unit are described as durable construction features.
The sensor control unit comes factory pre-calibrated and includes an integrated heater with a self-reset feature. Bosch says this design does not require baseline mapping, flow calculations, or learning cycles. These details make it a strong option when the exact Bosch part number matches the vehicle’s required replacement.
Limitation: The listed service life is a manufacturer claim, not a guarantee for every vehicle or operating condition. Verify the part number and application before purchase.
DEP PM Sensor For Select Heavy-Duty Trucks
Best for: Owners or service buyers working with listed Detroit Diesel DD13, DD15, or DD16 engines, plus select Cummins and PACCAR setups. The listing says the sensor measures fine particle concentrations and sends feedback to the engine control unit.
It references replacement numbers 0281007975, A0111531328, A0101538528, 5461552, 4384376, and 4359574. Choose this sensor if one of those numbers matches the part being replaced and the engine application is confirmed. The stated direct-fit design is intended to simplify installation on compatible setups.
Limitation: “Select” Cummins and PACCAR applications are not fully identified in the supplied details. Check the truck’s exact engine and part number rather than relying on brand alone.
68250217AA Sensor For Listed Ram 1500 Models
Best for: Buyers whose vehicle matches the listing’s 2014–2015 Ram 1500 application and required part number 68250217AA. The product description says it measures particulate matter in exhaust and is built to withstand high temperatures.
The listing also claims quicker response and stable performance, and says the sensor supports emission control and fuel-injection adjustment. These are product-description claims; the most useful selection check is whether the vehicle’s existing sensor number and application match the listing.
Limitation: The provided fitment information is limited to 2014–2015 Ram 1500. Do not assume it fits other Ram years, engines, or models without checking a reliable parts reference.
Jaguar Diesel PM Sensor With Listed Part Numbers
Best for: Buyers servicing a diesel Jaguar listed for the 2015–2021 range, including specified E-Pace, F-Pace, XE, and XF model codes. The listing gives HJ32-5H310-AC and 0281007266 as reference numbers.
Its described metal housing and electronic components are intended for operation in high-temperature and dusty environments. The product is presented as a real-time exhaust particulate monitor with fast signal response and resistance to interference. Choose it only after confirming the model, engine, year, and part number.
Limitation: The listing covers several model names and engine sizes, but the supplied details do not establish fitment for every configuration. Match the original sensor number before ordering.
0281006382 Diesel PM Sensor
Best for: Buyers whose parts information specifically calls for 0281006382. The listing describes a stainless steel, high-temperature-resistant housing and ceramic or semiconductor sensing elements, with protective measures for vibration and shock.
The sensor is described as a compact, sealed assembly that monitors particulate concentration and provides fast signal acquisition. Its stated design priorities include reducing signal interference and delivering stable data to vehicle control systems. It is a part-number-led option rather than a clearly identified vehicle-specific choice.
Limitation: The supplied product details do not name compatible makes, models, or engines. Confirm 0281006382 against the vehicle’s parts catalog or original sensor before choosing it.
Buying Guide: How To Choose A Diesel PM Sensor
Does the part number match the original sensor?
Start with the number printed on the existing sensor or specified by a trusted parts catalog. A matching number is more useful than a broad description such as “diesel particulate matter sensor.” Compare every listed reference number, including letter suffixes, because similar numbers may not indicate the same application.
Is the sensor intended for your vehicle and engine?
Check year, make, model, engine, and—when relevant—commercial engine family. The DEP listing names several heavy-duty engines but leaves some applications unspecified. The Ram and Jaguar listings provide narrower vehicle information, which still needs confirmation for the exact configuration.
What features matter for replacement?
- Calibration: Bosch specifically describes its sensor control unit as factory pre-calibrated.
- Construction: Compare stated housing materials and environmental design features, but treat product claims as descriptions rather than guarantees.
- Installation: Confirm connector, wiring, and mounting details with the vehicle’s service information or the seller before fitting.
- Diagnosis: A warning light or emissions fault does not by itself prove the sensor is defective; diagnosis can help avoid replacing the wrong component.
Should you choose a broad or vehicle-specific listing?
Choose a vehicle-specific listing when it clearly matches the vehicle and original part number. A part-number-focused sensor may suit several applications, but it requires more careful cross-referencing. If fitment remains uncertain, verify with a qualified parts supplier or mechanic before ordering.
Frequently Asked Questions
What does a diesel particulate matter sensor do?
It monitors particulate matter in diesel exhaust and sends information to vehicle control systems. That information can support emissions and exhaust-system monitoring.
Is a particulate matter sensor the same as a DPF sensor?
The term “DPF sensor” can refer to different components. Check the exact sensor type and part number; do not assume a pressure sensor and a particulate matter sensor are interchangeable.
Can I select a sensor by vehicle make alone?
No. Confirm the model year, engine, and replacement part number because fitment can vary within one make or model line.
Does a pre-calibrated sensor need programming?
Bosch states that its listed sensor control unit is factory pre-calibrated and does not require baseline mapping, flow calculations, or learning cycles. Requirements for other products are not specified here.
What should I verify before ordering?
Compare the original sensor number, vehicle and engine details, connector and mounting configuration, and the listing’s stated fitment. Resolve discrepancies before purchase.
