Repair and operation of the car

The check of usefulness of a state and substitution of the sensor of the temperature of cooling the liquid of the motor (EST)

To check

ORDER OF REALIZATION

1. Eat it the sensor represents a thermistor (the resistor that the resistance modifies with the modification of the temperature). The modification of the resistance of the sensor practises the straight influence in the vastness of the sign given by the sensor in ECM/PCM. At the same time with the REDUCTION of the resistance of temperature of the sensor IT INCREASES and vice-versa. In the presence in the memory of ECM/PCM of the corresponding code of the bad functioning (to see the System of the diagnostic one of side (OBD) - the beginning of the functioning and the codes of the bad functioning) is necessary to check that a condition of a chain eats and if an electrical system as it must must substitute the sensor. 2. The control of the sensor happens for the measurement of his resistance (companion sees an illustration) in a cold state (10 °C÷27 of °C). then the motor begins and heat it up to the temperature of normal work. The resistance of the sensor will fall. 3. The voltage of provision of measure in the capture of a black-red wire of the capture of an electrical system of the sensor in the included ignition (they do not begin the motor). The result of the measurement will do approximately 5,0 in, otherwise the interval checks a wire in the siege of the sensor to ECM/PCM.

Substitution

Before the initial implementation of the proceeding, hope for the cooling full of the motor.

ORDER OF REALIZATION

1. Before the installation of the new sensor his part of woodcarving must be injured with a fighter strip of teflon (movie FUM). 2. Pull out a uvula of lock, then exactly the sensor results. For aims of the reduction to the losses minimum of cooling the liquid they screw the new sensor it as soon as possible. Negotiate he eats it the sensor as it is possible more carefully as his damage is able to practise the perceptible impact in the functioning of a system of provision of power in general. 3. The installation is done upside-down. In the conclusion check the level of cooling the liquid, in case of the necessity they do the corresponding agreement (to see the Front Regular maintenance).
