How many coolant temperature sensors does the Mercedes-Benz E200 have?
1 Answers
Mercedes-Benz E200 has 2 coolant temperature sensors. Introduction to coolant temperature sensor: The coolant level and temperature sensor consists of a thermostat section and a water level control section, with matching components including a pressure reducing device before the electric valve and a rotary muffler heater for heating. Function of coolant temperature sensor: The temperature sensor converts coolant temperature into electrical signals to adjust fuel injection quantity (increasing injection during cold starts), modify ignition timing (advancing timing at low temperatures while delaying it at high temperatures to prevent knocking), and influence idle control valve operation (ECU controls idle speed based on sensor signals during cold starts to increase RPM).
