To check the flowmeter, follow these steps:

1. In a car with the engine switched off, disconnect the connector with the contacts from the controller. Then you need to turn on the ignition, but do not start the power unit. A multimeter is needed to check the voltage between the contact elements;
2. The sensor connector is equipped with five pins, the countdown is to the left, when viewed from the air flow from the filter. Between contacts 2 and 3 the rated voltage should be 10 volts, between 3 and 4 - 5 V. If there is a deviation, it is necessary to diagnose the integrity of the electrical circuit for precipices and leakage current;
3. Under normal ignition values, the resistance between the "ground" and the fifth pin must be switched off and checked. The resulting parameter should be about 4-6 pcs. If the value obtained is 0 ohms, the sensor must be replaced. Also, the problem may be a short to ground. If the resistance parameter is 100 kО, the cause must be found in the power failure or engine control unit.
