Bosch 0280130055 OE Engine Coolant Temperature Sensor

The Bosch 0280130055 is an Original Equipment (OE) quality engine coolant temperature sensor (ECT sensor) designed to deliver accurate, real-time coolant temperature readings to the engine control unit (ECU). Built to the same specifications as the sensors Bosch supplies directly to vehicle manufacturers, this replacement sensor helps restore proper engine management function, fuel efficiency, and emissions performance.

Bosch coolant temperature sensors utilize a Negative Temperature Coefficient (NTC) thermistor element, which provides a precise and responsive electrical signal that the ECU uses to regulate fuel delivery, ignition timing, cooling fan operation, and cold-start enrichment strategies.

Key Features:

• Original Equipment (OE) specification — built to the same standards as factory-installed sensors
• NTC thermistor design for fast, accurate temperature response
• 2-terminal connector configuration
• Durable construction engineered to withstand high engine bay temperatures and coolant exposure
• OEM Cross-Reference: 13621433077 (BMW)
• Direct fit — no modification required

As the world's largest automotive supplier, Bosch has been engineering precision sensors and engine management components for over a century. The 0280130055 is a trusted, direct-replacement coolant temperature sensor for select BMW and Saab vehicles, ensuring your engine management system receives the accurate data it needs to perform optimally.
