Which fuse is removed in the Toyota throttle body matching method?
1 Answers
Toyota throttle body matching method involves removing the EFI and ETCS fuses from the engine compartment fuse box. Relevant information about the throttle body is as follows: 1. Throttle body: It is a controllable valve that regulates air intake into the engine, available in two types - traditional cable-operated and electronic throttle. 2. Location: Connected to the air filter at the top and the engine block at the bottom, it is referred to as the throat of the automobile engine. Throttle body maintenance methods are as follows: 1. Gas release: Engine oil volatilizes when heated during use. The longer the usage period and the higher the temperature, the stronger the volatilization. Additionally, some cylinder compression gases inevitably squeeze into the crankcase through piston ring gaps, necessitating a gas release channel to prevent positive pressure formation in the oil pan. 2. Negative pressure extraction: The crankcase ventilation tube connects to the throttle body partly for environmental requirements and partly to utilize intake negative pressure to extract gases from the crankcase. When oil vapor reaches the intake pipe and cools, the oil condenses on the intake tract and throttle body, carrying along carbon deposits from the vapor which also settle in these areas. Since the throttle body opening has the highest airflow through its narrow gap and the gas temperature is lowest here, this area is most prone to condensation. 3. Cleaning frequency: How quickly the throttle body gets dirty depends on multiple factors including air filter quality, brand and quality of engine oil used, driving route conditions, air temperature conditions, engine operating temperature, and driving habits.
