Volkswagen Idle Jitter No Fault Code Unplug the sensor OK.

It is normal for Volkswagen idle jitter to pull out the sensor without fault code because the intake pressure data fluctuates too much. According to the relevant public information, it is normal to unplug the sensor because the intake pressure data fluctuates too much. The normal idle intake pressure is 300 mbar. If there is no air leakage in the air intake system, the air intake pressure is normal. The way to judge whether the intake pressure is normal is to turn off the engine, turn on the key and check that the intake pressure data is 1000mbar. If the intake pressure sensor is also normal, the fault is caused by the wrong valve timing of the camshaft.
