Two technicians are discussing a stepped ECT circuit. Technician A says that the sensor used for a stepped circuit is different
from the one used in a non-stepped circuit. Technician B says that a stepped ECT circuit uses different internal resistance inside the PCM. Who is right? A) Technician A B) Technician B C) Both technicians D) Neither technician
Explanation:ECT(ENGINE COOLANT TEMPERATURE) is a sensor present in the coolant Temperature sensor that checks and transmits the Temperature to the ECM(engine control module). This helps to regulate the fueling time, speed and other factors that can impact the Temperature of the engine.
Stepped ECT circuits require different Internal resistance inside the PCM(power-train control module) is a combined control which includes the ECU(ENGINE CONTROL UNIT) AND TCU(TRANSMISSION CONTROL UNIT). The same sensor can be used for both the stepped circuit and a circuit that is not stepped.
Lavoisier’s oxygen theory of combustion was one of his most
notable contribution to science and earned him the title of the “father of
modern chemistry”. He recognized the combustible property of oxygen and that phosphorus and other metallic elements increased in terms of weight when burned.
