Is the throttle hose pressure high?

Throttle pipe pressure is not high. According to car home's data, it is normal that the water pipe pressure of the throttle valve is generally between 80KPA, so the pressure is not great. If the pressure is too high, there is a fault. The possible reason for the high absolute pressure of the intake pipe is that the intake pipe behind the throttle valve is not sealed. The fuel filler cap is not sealed properly; The fuel tank exhaust system is not sealed; Crankcase ventilation system is not sealed; Adjustable camshaft control device is not flexible.
