LaVida 1.4T intake pipe pressure signal is too small.

1. Due to pipeline rupture, the pressure signal of intake pipe is too small. Check whether the pipeline is broken.

2. Intake pipe pressure will be affected by throttle opening, engine speed and sealing performance. The smaller the throttle opening, the greater the suction effect formed by the piston during intake, the greater the intake pipe suction, the greater the vacuum degree, the lower the intake pipe pressure, the higher the engine speed, the greater the suction effect formed by the piston during intake, the greater the intake pipe suction, the greater the vacuum degree and the lower the intake pipe pressure. The better the sealing performance, the greater the intake manifold suction, the greater the vacuum degree and the smaller the intake manifold pressure. It may be that the air intake is large when idling, so the sensor signal voltage is high. The solution is to use fuel-efficient semi-automatic idle motor.
