Ford Focus>> Ignition system>> Work with ignition system>> Check of the sensor of pressure of air in an inlet collector
For check of the sensor of pressure of air execute the following:
- remove a hose from the sensor of pressure and close a hose opening a finger;
- start the engine by means of the assistant and finish frequency of rotation of a cranked shaft to 2000 mines-1;
- at such indicator of frequency of rotation again connect a hose to the sensor;
- as on the sensor again there was a vacuum, the control unit should correct the ignition moment. At the identical provision of a pedal of an accelerator frequency of rotation of a cranked shaft should increase;
- if frequency of rotation remains to a constant, it indicates a leakage of a hose or malfunction of the sensor of pressure. The engine reacts to it decrease in capacity and increase in toxicity of the fulfilled gases.
