7.10.5. Check of sensors of control devices

Sensor of the index of temperature of cooling liquid
The thermoresistor changing the resistance depending on temperature of cooling liquid is installed in the sensor. Data for check of the sensor are provided in tab. 7.12.

Sensor of a control lamp of pressure of oil. The sensor is installed on a head of cylinders of the engine. Contacts of the sensor have to become isolated and be disconnected with a pressure of 20-60 kPa (0,2–0,6 kgfs/cm2).
Sensor of the index of level of fuel.
The sensor is combined with the electrogasoline pump established in the fuel tank. The sensor has the variable resistor from a nikhromovy wire. The mobile contact of the resistor moves the lever with a float.
At an empty tank resistance of the sensor has to be 315–345 Ohms, with the tank filled half – 108–128 Ohms, and at a full tank — no more than 7 Ohms.
Speed sensor
Microelectronic, works at a basis of "Hall's effect" and gives impulses of squared tension. The output tension of low level of an impulse has to be no more than 1 V, and high level — not less than 5 Century.
To one kilometer of the passable way there correspond 6000 impulses of the sensor.
