Owners of a VAZ 2110 car must have information about all the main sensors of the car. They ensure stable engine performance. You also need to be able to check them correctly.
Instructions
Step 1
First, pay attention to the coolant temperature sensor. It is a thermistor. This sensor is wrapped in the coolant outlet pipe located on the cylinder head. At low temperatures, the resistance of the sensor should be high, and at high temperatures, low.
Step 2
The coolant temperature is calculated by the controller. It is this temperature that affects most of the characteristics that the controller controls.
Step 3
The knock sensor is also of great importance. It is wrapped around the top of the cylinder block. Its main task is to capture abnormal vibrations in a car engine. The most sensitive element of this sensor is a piezoelectric crystal plate. When detonation occurs, voltage pulses are generated at the output. They are capable of increasing with increasing intensity of detonation impacts. The sensor gives a signal, and the controller adjusts the ignition timing. Thus, the elimination of detonation flashes of fuel occurs.
Step 4
Pay attention to the oxygen concentration sensor. It is installed on the front exhaust pipe. The oxygen in the exhaust gas reacts with this sensor, creating a potential difference at the output of the sensor. There is a change from 0.1V to 0.9V. For the sensor to concentrate oxygen normally, it must have a temperature above 360 ° C. For this purpose, a heating element is installed in it. It is able to warm up the sensor to the required temperature in a short time. Thanks to the sensor, the controller determines which command to adjust the composition of the working mixture to send to the injectors. With a lean mixture, a command is given for enrichment, and with a rich mixture, a command for depletion is given.
