0281007411 Bosch Particulate matter probe

This little guy measures the amount of soot—tiny particles—coming out of your exhaust. It’s basically an electronic sensor that detects those particles and sends a signal to the engine control unit, or computer. It doesn’t directly measure oxygen, even though you'll find it listed near oxygen sensors sometimes. It’s about the stuff coming out with the exhaust, not the oxygen content itself. It’s a pretty sophisticated piece of tech, actually, because it has to be able to withstand extremely high temperatures and harsh exhaust gases. It’s primarily used in diesel vehicles with diesel particulate filters—DPFs. The DPF is what actually traps the soot, and this probe tells the engine how clogged that filter is getting. The engine then uses that information to decide when to regenerate—basically, burn off the collected soot. It’s a key part of making sure your car meets emissions standards and runs efficiently. It acts like a shield for the catalytic converter, preventing overload and damage from excessive soot. If this probe goes bad, your engine might have trouble accurately assessing how clogged your DPF is. You’ll notice if it's failing because you might get a check engine light, potentially with codes related to DPF performance or emissions. The engine could try to regenerate the DPF too often or not often enough. That can lead to reduced fuel economy, lost power, and, ultimately, expensive damage to the DPF or other exhaust components. It’s one of those parts where addressing a problem early can save you a lot of money and headaches down the road.
