0281006552 Bosch Particulate matter probe

This little guy basically measures the amount of soot, or particulate matter, coming out of your exhaust. It’s an electronic sensor that sends a signal to your engine computer, telling it how much soot is building up. It doesn't directly measure oxygen, although it falls into the same general family of sensors as an oxygen sensor, that’s why you find it listed alongside them. It’s all about monitoring emissions and keeping things clean. It’s a crucial part of your diesel particulate filter, or DPF, system. Modern diesel engines use these filters to trap soot and keep it from going into the air. The PM probe tells the engine when the DPF is getting full. Then, the engine initiates a “regeneration” process – basically a controlled burn to clear out the soot. Without an accurate reading from this probe, the engine won't know when to regenerate, or it might try to regenerate too often, which can cause problems. It's really the eyes for that whole system. If this probe fails, you'll likely see a check engine light, and it could trigger a whole bunch of other issues. You might notice reduced engine performance, increased fuel consumption, and even damage to the DPF itself if it gets too clogged. It acts like a shield for your DPF, preventing it from getting overwhelmed. If you’re experiencing issues with your DPF, a faulty PM probe is a really common culprit. You can often find a replacement easily enough, even online at places like Fixparts Online, but getting the right one is key. If it’s throwing codes, it’s best to get it looked at sooner rather than later, before it turns into a bigger, more expensive fix. More than just a part: Particulate Matter Probe (MPN 0281006552) includes a 12-month warranty!
