What is the reason for the high pressure of Cruze engine?

Cruze engine pressure is too high, and the throttle opening becomes larger. When the engine idle speed is too low, you can delete the engine adjustment value. It is the sealing performance, which is the most important part. Check whether the intake manifold is damaged and whether the sealing ring of the engine intake is installed correctly. Otherwise, you can only suspect that the absolute pressure sensor is damaged: try to analyze the throttle opening-suction pipe pressure. Contrast: the pressure is too low, propose a solution. The intake manifold pressure sensor has a signal wire and a ground wire. Grounding the signal line will increase the resistance and voltage. Short circuit or open circuit of signal line will lead to the failure of speed increase, and the refueling will be closed. Sensor aging will lead to abnormal intake pressure.
