This little guy basically measures the temperature of the exhaust gases coming out of your engine. It’s a pretty straightforward job – it sends a signal to the engine’s computer letting it know how hot things are getting after combustion. It’s a resistor, really; its electrical resistance changes with temperature, and the computer reads that change. Now, the engine computer uses that temperature reading for a few things. Primarily, it helps control the catalytic converter. Think of the converter as cleaning up the exhaust – it needs to get hot enough to work efficiently. This sensor tells the computer if the converter is reaching its ideal operating temperature. It also plays a role in diesel particulate filter regeneration, making sure the system is burning off soot correctly. If this sensor goes bad, it can cause a whole lot of issues. You might see a check engine light come on, naturally. But more seriously, it can cause the engine to run poorly, reduce fuel economy, and even damage the catalytic converter or diesel particulate filter. Those are expensive parts to replace, so addressing this sensor is a good preventative step. You’ll notice if it's failing because the engine light will likely illuminate, and you might feel a loss of power. You can find these pretty easily; Fixparts Online has a good selection if you’re looking to do the repair yourself. Replacing it is usually a pretty simple job, though it depends on where it’s located on your vehicle.
