Toyota RAV4>> The monitoring system and decrease in toxicity of the fulfilled gases>> Sensors and valves of system of injection of fuel (EFI)>> Replacement of the sensor of temperature of cooling liquid (ECT)
The sensor of temperature of cooling liquid represents the thermoresistor, i.e. the resistor which resistance changes depending on temperature. At temperature reduction resistance of the sensor increases and on the contrary (see specifications).
Replacement of the sensor of temperature of cooling liquid make on the cold engine as follows:
– switch off ignition and disconnect a "weight" wire from the storage battery;
– merge from system of cooling of 4 l of cooling liquid;

Fig. 7.11. An arrangement of the sensor of temperature of cooling liquid (ECT) on models till 2001


– disconnect from the ECT sensor the electric socket and turn out the sensor (fig. 7.11) ;
Address with the sensor very carefully as its damage will lead to failure of system of injection of fuel.
Installation carry out to sequences, return to removal. Before installation wrap up a sensor carving the teflon tape excluding formation of corrosion and preventing leaks.
