MAN 81274210215 Temperature Sensor

Description

The MAN 81274210215 is a temperature sensor used within engine systems to monitor critical operating temperatures. This sensor is crucial for ensuring optimal engine performance and preventing overheating. The device measures temperature and transmits this data to the engine control unit (ECU), enabling precise adjustments to fuel delivery and ignition timing. Its dimensions are 10 x 10 x 370 mm. By providing accurate temperature readings, this sensor contributes to improved fuel efficiency, reduced emissions, and enhanced engine longevity.

Key Features & Benefits

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.

Symptoms, Risks & Replacements

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.
