а как нибуть по проще можно
Куда ж проще?
МАП сенсор тю-тю, холостой не регулируется. Может быть забита трубка на него, попорчен разъём или проводка.
Вот методика проверки из того же документа, что и коды ошибок. Могу перевести, но проще скормить этот текст в
http://translate.google.com6 MANIFOLD ABSOLUTE PRESSURE SENSOR:
This produces a voltage of 0.5 to 4.5v dependant upon the pressure/vacuum in the inlet manifold.
The connector usually has three terminals. Use a voltage meter to identify the 5 volt supply, the ground, and the output voltage of the sensor.
Test the response of the sensor output relative to engine speed as for (1). If there is little or no response, disconnect the vacuum pipe from the sensor and apply a vacuum directly to the sensor. If the voltage now varies, check the vacuum pipe for leaks or blockages. If the voltage does not vary with a direct vacuum, it is likely that the sensor is defective.
To positively identify the MAP sensor as faulty, use a Sensor Simulator to simulate the output of the sensor.
