Engine Coolant Temperature Sensor – 0009056102OE | Mercedes Sprinter Coolant Temp Sensor

SKU: 0009056102OE - qty 1

Help your Mercedes Sprinter maintain accurate engine temperature monitoring with the Engine Coolant Temperature Sensor – part #0009056102OE. This sensor is a critical part of your Sprinter’s cooling system and engine management, measuring the temperature of the engine coolant and sending that data to the engine control unit (ECU). The ECU uses this information to adjust fuel delivery, ignition timing, fan control, and emissions systems. A worn or faulty coolant temperature sensor can lead to erratic temperature readings, poor fuel economy, rough idle, overheating, or dashboard warning lights — replacing it with a proper sensor restores reliable engine feedback and performance. 

✔ OEM-Equivalent Coolant Temp Sensor

• Designed to match Mercedes-Benz part number 0009056102 / A0009056102 for accurate fit and operation in Sprinter diesel engines. 

• Direct-fit replacement for the original sensor installed at the engine coolant passage (cylinder head or engine block). 

✔ Critical Engine Data for ECU

• Measures engine coolant temperature and sends real-time data to the ECU to help control fuel mixture and cooling system operation. 

• Helps the vehicle maintain proper engine warm-up behavior, cooling fan activation, and fuel efficiency under varying conditions. 

✔ Reliable & Easy to Install

• Built with durable materials to withstand heat, vibration, and repeated thermal cycling typical of diesel engine operation. 

• Plug-and-play design makes installation straightforward — ensure sensor connector and coolant are handled safely.

📌 Pro Tip: When replacing the coolant temperature sensor, it’s a good idea to inspect the coolant level and thermostat, as these components work together to support engine thermal control.
