13621709967 BMW SENSOR

This little guy basically reads how hot your engine is. It’s constantly monitoring the temperature of the coolant flowing through your engine, and then sends that information as an electrical signal to your car’s computer – the Engine Control Unit, or ECU. It’s a pretty straightforward job, just reporting temperature. Now, that temperature reading isn't just for the gauge on your dashboard, though it does send info for that. The ECU uses that temperature data to make a lot of important decisions. It adjusts the fuel mixture—more fuel needed when the engine is cold, less when it's hot. It controls the timing of the ignition, and it even affects how the emissions system operates. It’s involved in things like whether or not the electric cooling fan kicks on, too. Think of it as a key piece of information the computer needs to run the engine properly. If this sensor goes bad, it can cause a whole range of problems. Sometimes it sends a completely wrong reading, which can make your engine run too rich or too lean. You’ll notice if that happens – rough idling, poor fuel economy, maybe even trouble starting. Other times, it might just send no signal at all, which will usually trigger a check engine light. Ignoring it can lead to more serious engine damage over time, because the computer is making decisions based on bad information. A faulty sensor can really throw everything off. You can find these pretty easily online. Fixparts Online has a good selection, if you're looking for a replacement.
