Check the air flow sensor using the following procedure: - Disconnect the electrical connector of the air flowmeter;
| Fig. 204. view the inside of the plug blocks the air flow sensor: "1" and "4" - contacts for connecting diode lamps
|
- Connect the foot control diode lamp to the terminals "1" and "4" plug block (Fig. 204); - With the help of an assistant start the engine. If the lamp lights up, then, consequently, electric current is supplied to the air flow sensor.
