The high voltage of the intake pressure sensor line is the leakage of the intake system, that is, the leakage of the throttle valve and the inlet pipe connection, resulting in the internal vacuum beyond the range of the pressure sensor, then the voltage signal given by the pressure sensor will exceed the range specified by the computer, so the fault code will be reported, and the throttle can be reinstalled to solve the fault. The specific steps are as follows:
< br >
1. Remove the intake hose.

2. Unscrew the throttle fixing screw.

3. Remove the throttle.

4. Replace the throttle pad.
