All modern vehicles consist of several independent operating systems controlled by a main system processor with independent sub-processors. The sub-processors provide class 2 serial information data to the main processor while handling the operation of the system and carry the circuit load to protect the main operating system. When replacing any level processor programming may be needed to enter the unit into the vehicles main operating system.

The engine coolant temperature sender, not to be confused with the engine coolant temperature sensor, is located anywhere within the engine cooling system and contains a thermistor that changes in resistance value as the thermistors ambient temperature changes. The engine coolant temperature sender is fed 12 volts and is typically used in conjunction with a gauge in the instrument cluster to provide a visual representation of the engine coolant temperature condition.

Product Features:

• Tin plated lead frame prevents corrosion and ensures a reliable terminal connection under adverse ambient conditions.
• Lead frame terminal size and location determined using image dimension measuring system or 3D laser scanner.
• Thermally conductive grease within the housing providing the most accurate temperature transfer from the engine to the thermistor.
• Plated brass or aluminum housings to prevent housing corrosion, ensures effective heat distribution to thermal element, and ensure a secure and leak-free thread mount.
• Computer-Aided Design (CAD), laser scanning and 3D printing – utilizing Fused Deposition Modeling (FDM) and Stereolithography (SLA) – in the connector terminal design process ensures speed-to-market and a precise connector fit guaranteed.
