Toyota RAV4>> The control system and decrease in toxicity of the fulfilled gases>> Sensors and valves of system of injection of fuel (EFI)>> Replacement of the sensor of absolute pressure of air in an inlet collector on models since 2001
The sensor of absolute pressure of air in an inlet collector measures air pressure in an inlet collector which fluctuates depending on loading of the engine and speed of the car and transforms information to output tension. Output tension changes from 1,9 to 2,1 In at the gate (high vacuum) closed throttle and from 0,3 to 0,5 In at an open butterfly valve (low vacuum). On the basis of this tension of PCM operates supply of fuel and installation of a corner of an advancing of ignition. The sensor is fixed on the arm established on a partition of a motor compartment.
You make replacement of the sensor of absolute pressure in an inlet collector on models since 2001 as follows:
– switch off ignition and disconnect a wire of "weight" from the rechargeable battery;
– disconnect the electric socket and a vacuum hose from the sensor;

Fig. 7.8. The sensor of absolute pressure in an inlet collector: 1 – vacuum hose; 2 – the sensor of absolute pressure in an inlet collector; 3 – clip of fastening of a wire of the sensor; 4 – electric socket


– turn out a bolt and remove the sensor of absolute pressure together with an arm from a partition of a motor compartment (fig. 7.8) .
You carry out installation to the sequences, the return to removal.
