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 the air temperature arriving in the engine (IAT) on models till 2001
On models since 2001 the sensor of temperature of air arriving in the engine is built in the sensor of a measuring instrument of a consumption of air (MAF).
The sensor of the air temperature, arriving in the engine, 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 the air temperature arriving in the engine (IAT), on models till 2001 see off as follows:
– switch off ignition and disconnect a "weight" wire from the storage battery;

Fig. 7.10. An arrangement of the sensor of the air temperature arriving in the engine (IAT), on models of 1996


– disconnect from the IAT sensor the electric socket (fig. 7.10) ;
– take the IAT sensor from the case of the air filter.
Installation проводиту in sequence, return to removal.
