81.27421-0164 MAN TEMPERATURE SENSOR

This temperature sensor, manufactured by MAN with MPN 81274210164, is a critical component within an engine’s electronic system. It accurately monitors engine temperature, providing data to the engine control unit (ECU) for optimal performance and emissions control. This sensor is commonly used in diesel engines to prevent overheating and ensure efficient combustion. The sensor’s precise measurements contribute to improved fuel economy, reduced wear, and extended engine life. It measures 20 x 22 x 55 mm and is manufactured in Germany. This little guy measures the temperature of either the engine coolant or sometimes the intake air, depending on which one you need. It's a pretty simple job, really – it takes a temperature reading and sends that information as an electrical signal to the car’s computer, the ECU. That signal lets the computer know how warm or cold things are running. It’s a key piece in a lot of different systems. The ECU uses that temperature information to adjust things like the fuel mixture, ignition timing, and even whether the cooling fan kicks on. It's essential for keeping the engine running smoothly and efficiently. It also plays a role in things like your temperature gauge on the dashboard, and can even affect how the AC system works. If this sensor goes bad, things can get messy. You might notice your engine running poorly – maybe rough idling, trouble starting, or even a check engine light. Sometimes, you’ll notice if your temperature gauge is reading incorrectly, swinging wildly, or just staying stuck. More seriously, a faulty sensor can cause the engine to overheat or, conversely, run overly rich, potentially damaging the catalytic converter. It's one of those parts that doesn’t always give a huge, obvious sign it’s failing, but it’s crucial for preventing bigger problems down the road. We often have these in stock, and you can find a good selection at places like Fixparts Online if you prefer to look yourself. It’s a relatively inexpensive part to replace, but it can save you a lot of headaches. Get more value: Temperature Sensor (MPN 81274210164) is protected by a 12-month warranty!
