What causes the high intake pressure of intake pressure sensor detected by Li Xia A+ engine computer?

It shows that the computer has encountered a logical error. The throttle position sensor shows that the throttle valve is not open and the idle valve is not fully open, but the pressure sensor shows that the pressure in the intake manifold is high, so the intake pressure of the intake pressure sensor shows that there is air leakage. This phenomenon also occurs at high engine speed, and the pressure sensor estimates that it is normal.

If everything is normal after restarting after the flameout, it may be that the idle valve is out of control or there is air leakage somewhere in the intake manifold. You can try to unplug the spare motor line when it is normal to see if it is normal.
