Where is the coolant temperature sensor located on a Honda 2.4 engine?
1 Answers
Honda 2.4 engine's coolant temperature sensor is located on the radiator, positioned below the radiator's electric fan. It is situated next to the transmission cooling pipe. Composition of the coolant temperature sensor: The coolant temperature and level sensor consists of a thermostat section and a water level control section. It is also accompanied by a pressure reduction device in front of the electric valve and a rotary muffler heater for heating. Function of the coolant temperature sensor: The coolant temperature sensor converts the coolant temperature into an electrical signal, which is input to the ECU to: Adjust the fuel injection quantity; increase fuel injection during low temperatures. Adjust the ignition timing; advance the ignition timing during low temperatures and retard it during high temperatures to prevent knocking. Influence the idle control valve; during low temperatures, the ECU controls the idle control valve based on the coolant temperature sensor signal to increase idle speed, affecting the EGR valve.
