F00099P402 Bosch Pressure/Temperat Sensor

This sensor actually does two jobs in one. It measures both the coolant temperature and the pressure in the engine’s cooling system. It sends that info—temperature and pressure—as electrical signals to the engine control unit, or ECU—that's basically the car’s computer. Think of it as a really important messenger. The ECU uses that information to make all sorts of decisions. It helps determine things like how long the engine needs to warm up, when to turn on the radiator fan, and even how the engine is running overall. It’s a key piece in keeping everything running smoothly and at the right temperature. A lot of modern vehicles also use this signal for things like displaying the temperature gauge on your dashboard. If this sensor goes bad, it throws everything off. The ECU gets inaccurate data, and that can lead to all sorts of problems. You might notice your engine overheating because the fan isn't kicking on when it should. You could experience poor fuel economy, rough idling, or even the check engine light illuminating. Sometimes the symptoms are subtle, but left unchecked it can cause real damage. You’ll notice if your temperature gauge starts reading oddly—either consistently high or low, or fluctuating wildly. You can often find a replacement for a pretty good price at places like Fixparts Online. It’s a relatively inexpensive part to replace, and can save you a lot of headaches—and bigger repair bills—down the road. Competitive edge: Pressure Temperature Sensor (MPN F00099P402) includes a 12-month warranty!
